                                3COM CORPORATION

                              EMPLOYMENT AGREEMENT

This Employment Agreement (the "Agreement") is by and between 3Com Corporation
(the "Company) and Robert Y. L. Mao ("Executive") and is as of August 7, 2006.

1. Duties and Scope of Employment.

     (a) Positions and Duties. As of August 18, 2006 (the "Effective Date"),
Executive will serve as the Company's Executive Vice President, Corporate
Development and shall report directly to the Chief Executive Officer. As soon as
reasonably practicable thereafter, Executive will be appointed to the Board of
Directors of Huawei-3Com Co., Ltd. "H3C"). Executive's principal place of
employment will be in Beijing, China with regular travel to Hangzhou, China.
Executive shall render such business and professional services in the
performance of his duties, consistent with the terms of this Agreement and
Executive's position within the Company, as will reasonably be assigned to him
by the Chief Executive Officer. The period Executive is employed by the Company
under this Agreement is referred to herein as the "Employment Term."

     (b) Obligations. During the Employment Term, Executive will devote
Executive's full business efforts and time to the Company and will use good
faith efforts to discharge Executive's obligations under this Agreement to the
best of Executive's ability and in accordance with each of the Company's
corporate guidance and ethics guidelines, conflict of interests policies and
code of conduct. For the duration of the Employment Term, Executive agrees not
to actively engage in any other employment, occupation, or consulting activity,
including membership of boards of directors, for any direct or indirect
remuneration without the prior approval of the Board (which approval will not be
unreasonably withheld); provided, however, that Executive may (i) serve on the
boards of directors of or continue to hold an interest in the companies
previously disclosed and submitted to the Company in writing prior to the
Effective Date and (ii) without the approval of the Board, serve in any capacity
with any civic, educational, or charitable organization, provided such services
do not interfere with Executive's obligations to Company.

          (i) Executive hereby represents and warrants to the Company that
Executive is not party to any contract, understanding, agreement or policy,
written or otherwise, that would be breached (subject to the possible exception
referenced in Section 17 of this Agreement) by Executive's entering into, or
performing services under, this Agreement. Executive further represents that as
of the date of this Agreement there are no threatened, pending, or actual claims
against Executive of which he is aware as a result of his employment with his
current employer (or any other previous employer) or his membership on any
boards of directors.

     (c) Other Entities. Executive agrees to serve and may be appointed, without
additional compensation, as an officer and director for each of the Company's

                                       1

<PAGE>

subsidiaries, partnerships, joint ventures, limited liability companies and
other affiliates, including entities in which the Company has a significant
investment as determined by the Company. As used in this Agreement, the term
"affiliates" will include any entity controlled by, controlling, or under common
control of the Company.

2. At-Will Employment. Executive and the Company agree that Executive's
employment with the Company constitutes "at-will" employment. Executive and the
Company acknowledge that this employment relationship may be terminated at any
time, upon written notice to the other party, with or without Cause or Good
Reason (as each such term is defined in Section 10 below), at the option either
of the Company or the Executive. However, as described in this Agreement,
Executive may be entitled to severance benefits depending upon the circumstances
of Executive's termination of employment.

3. Compensation.

     (a) Base Salary. As of the Effective Date, the Company will pay Executive
an annual salary of $400,000.00 as compensation for his services (such annual
salary, as is then effective, to be referred to herein as "Base Salary"). The
Base Salary will be paid periodically in accordance with the Company's normal
payroll practices and be subject to the usual, required withholdings.

     (b) Annual Incentive. Executive will be eligible to receive annual cash
incentives payable for the achievement of performance goals established by the
Board of Directors of the Company (the "Board") or by the Compensation Committee
of the Board (the "Committee"). During the Employment Term, Executive's target
annual incentive ("Target Annual Incentive") will be not less than 100% of Base
Salary, with a maximum potential opportunity of 200% of Base Salary, subject to
the terms of the bonus plan approved by the Committee except that the terms of
this Agreement shall control to the extent that this Agreement provides for more
favorable terms with respect to the annual incentive as it applies to Executive.
The actual earned annual cash incentive, if any, payable to Executive for any
performance period will depend upon the extent to which the applicable
performance goal(s) specified by the Committee are achieved or exceeded and will
be adjusted for under- or over-performance. Any incentive earned during the
first half of fiscal 2007 will be pro-rated based on the Effective Date
(calculated by multiplying any incentive earned by Executive by a fraction with
a numerator equal to the number of days between the Effective Date and the close
of the first half of the fiscal year and a denominator equal to 182). The
Company will notify Executive of the performance goals in respect of fiscal 2007
within 60 days after the Effective Date.

     (c) Stock Options.

          (i) In connection with his initial service Executive will be granted
nonstatutory stock options to purchase 2,000,000 shares of Company common stock.
The exercise price of the first tranche of 1,000,000 options will be at a per
share exercise price equal to the closing price per share of Company common
stock on Nasdaq Global

                                       2

<PAGE>

Select Market ("Nasdaq") on the first Tuesday in the month immediately
succeeding the month in which Executive commences employment with the Company
(the "First Tuesday Exercise Price"). The second tranche of 1,000,000 options
will be awarded as soon as practicable after Executive becomes CEO of H3C in
accordance with the equity grant policy in effect at the time. No stock options
shall be deemed to have been accepted until Executive has signed the Company's
form of stock option agreement. The stock option grant described above will be
granted under and subject to the terms, definitions and provisions of the
Company's 2003 Stock Plan, as amended (the "2003 Plan"), and the Company's form
of stock option agreement, except that the terms of this Agreement shall control
to the extent that this Agreement provides for more favorable terms with respect
to the stock option grant. The stock option grant will be scheduled to vest at a
rate of 25% on each anniversary of the grants over four (4) years assuming
Executive's continued employment with the Company on each scheduled vesting
date, and will have the maximum term permitted in the 2003 Plan.

4. Employee Benefits.

     (a) Generally. Executive will be eligible to participate in accordance with
the terms of all Company employee benefit plans, policies and arrangements that
are applicable to other executive officers of the Company, as such plans,
policies and arrangements may exist from time to time.

     (b) Vacation. Executive will be entitled to receive paid annual vacation in
accordance with Company policy for other senior executive officers. In no event
will Executive receive less than four (4) weeks of paid vacation time per
calendar year.

5. Expenses. The Company will reimburse Executive for reasonable travel,
entertainment and other expenses incurred by Executive in the furtherance of the
performance of Executive's duties hereunder, in accordance with the Company's
expense reimbursement policy as in effect from time to time. Executive will be
provided access to a car and driver for his daily travel in connection with his
employment with the Company.

6. Term and Termination of Employment. In the event Executive's employment with
the Company terminates for any reason, Executive will be entitled to any (a)
unpaid Base Salary accrued up to the effective date of termination; (b) unpaid,
but earned and accrued annual incentive for any completed fiscal year as of his
termination of employment; (c) pay for accrued but unused vacation; (d) benefits
or compensation as provided under the terms of any employee benefit and

Incorporation, Bylaws, the Agreement, or separate indemnification agreement, as
applicable. In addition, if the termination is by the Company without Cause or
Executive resigns for Good Reason, Executive will be entitled to amounts and
benefits specified in Section 8.

     (b) Termination Without Cause or Resignation for Good Reason in Connection

9. Excise Tax Gross-Up. In the event that the benefits provided for in this
Agreement constitute "parachute payments" within the meaning of Section 280G of
the Internal Revenue Code of 1986, as amended (the "Code") and will be subject
to the excise tax imposed by Section 4999 of the Code, then Executive will
receive (i) a payment from the Company sufficient to pay such excise tax, and
(ii) an additional payment from the Company sufficient to pay the federal and
state and local income and employment taxes and additional excise taxes arising
from the payments made to Executive by the Company pursuant to this sentence.
However the Company may elect not to make payments under the preceding sentence
to the extent it reasonably determines that (a) the "parachute payments" arise
from the acceleration of options with exercise prices exceeding the price at
which the underlying shares could be sold on the date of the Change in Control
and (b) any payments under the preceding sentence would not significantly
benefit the Executive. Unless Executive and the Company agree otherwise in
writing, the determination of Executive's excise tax liability, if any, and the
amount, if any, required to be paid under this Section 9 will be made in writing
by a certified public accounting firm selected by the Company and reasonably
acceptable to the Executive (the "Accountants"). For purposes of making the
calculations required by this Section 9, the Accountants may make reasonable
assumptions and approximations concerning applicable taxes and may rely on
reasonable, good faith interpretations concerning the application of Sections
280G and 4999 of the Code. Executive and the Company agree to furnish such
information and documents as the Accountants may reasonably request in order to
make a determination under this Section 9. The Company will bear all costs the
Accountants may reasonably incur in connection with any calculations
contemplated by this Section 9.

10. Definitions.

     (a) Cause. For purposes of this Agreement, "Cause" will mean:

          (i) Executive's willful and continued failure to perform the duties
and responsibilities of his position after there has been delivered to Executive
a written demand for performance from the Board which describes in reasonable
detail the basis for the Board's belief that Executive has not substantially
performed his duties and provides Executive the opportunity to present to the
Board his good faith reasons for not so performing and, if the Board does not
agree with such reasons, with thirty (30) days to take corrective action;

          (ii) Any act of personal dishonesty taken by Executive in connection
with his responsibilities as an employee of the Company with the intention or
reasonable expectation that such action may result in the substantial personal
enrichment of Executive;

          (iii) Executive's conviction of, or plea of nolo contendere to, a
felony that the Board reasonably believes has had or will have a material
detrimental effect on the Company's reputation or business;

                                       6

influence, obstruct or impede, or (C) failing to materially cooperate with, any
investigation authorized by the Board or any governmental or self-regulatory

will mean the occurrence of any of the following events:

          (i) The consummation by the Company or by H3C of a merger or
consolidation with any other corporation, other than a merger or consolidation

represent (either by remaining outstanding or by being converted into voting
securities of the surviving entity) more than 50% of the total voting power
represented by the voting securities of the Company or the voting power of H3C
or such surviving entity outstanding immediately after such merger or
consolidation;

          (ii) The approval by the stockholders of the Company or H3C, or if

disposition by the Company or H3C of all or substantially all of the Company's
or H3C's assets;

          (iii) Any "person" (as such term is used in Sections 13(d) and 14(d)
of the Securities Exchange Act of 1934, as amended) becoming the "beneficial
owner" (as defined in Rule 13d-3 under said Act), directly or indirectly, of
securities of the Company or H3C representing 50% or more of the total voting

a majority are Incumbent Directors. "Incumbent Directors" will mean directors
who either (A) are directors of the Company as of the date hereof, or (B) are
elected, or nominated for election, to the Board with the affirmative votes of

benefits by a percentage reduction that is no greater than 15%;

          (iv) A reduction in Executive's Base Salary or annual cash incentive
as in effect immediately prior to such reduction other than pursuant to a
reduction that also is applied to substantially all other executive officers of
the Company and which reduction reduces the Base Salary and/or annual cash
incentive by a percentage reduction that is no greater than 15%;

fifty (50) miles from Beijing, China;

          (vi) The failure of the Company to obtain the assumption of the

     (e) In Connection with a Change of Control. For purposes of this Agreement,
a termination of Executive's employment with the Company is "in Connection with

months prior or twelve (12) months following a Change of Control.

11. Indemnification. Subject to applicable law, Executive will be provided
indemnification to the maximum extent permitted by the Company's Articles of
Incorporation or Bylaws, including, if applicable, any directors and officers

15. Severability. If any provision hereof becomes or is declared by a court of
competent jurisdiction to be illegal, unenforceable, or void, this Agreement
will continue in full force and effect without said provision.

16. Arbitration.

     (a) Except as provided below, any dispute arising out of or relating to
this Agreement or the breach, termination or validity hereof shall be finally
settled by binding arbitration conducted expeditiously in accordance with the
J.A.M.S./Endispute Streamlined Arbitration Rules and Procedures (the "J.A.M.S.
Rules"). The arbitration shall be governed by the United States Arbitration Act,
9 U.S.C. Sections 1-16, and judgment upon the award rendered by the arbitrators
may be entered by any court having jurisdiction thereof. The place of
arbitration shall be Boston, Massachusetts.

     (b) The parties covenant and agree that the arbitration shall commence
within 60 days of the date on which a written demand for arbitration is filed by
either party hereto. The parties (or their legal representatives) will promptly
confer to select a single arbitrator mutually acceptable to both parties. The
arbitrator must be a licensed attorney, primarily engaged as a practicing lawyer
in the field of employment law and related litigation for at least ten (10)
years, or primarily engaged in the practice of arbitrating or mediating
executive employment law disputes for at least ten (10) years, and must not have
any existing or prior relationship with the Company or any of its subsidiaries
or affiliates, on the one hand, or Executive, on the other hand.

If the parties are unable to agree upon an arbitrator, one will be selected,
meeting the above criteria, in accordance with the J.A.M.S. Rules. In connection
with the arbitration proceeding, the arbitrator shall have the power to order
the production of documents by each party and any third-party witnesses. In
addition, each party may take up to three (3) depositions as of right, and the
arbitrator may in his or her discretion allow additional depositions upon good
cause shown by the moving party. However, the arbitrator shall not have the
power to order the answering of interrogatories or the response to requests for
admission. In connection with any arbitration, each party shall provide to the
other, no later than seven (7) business days before the date of the arbitration,
the identity of all persons that may testify at the arbitration and a copy of
all documents that may be introduced at the arbitration or considered or used by
a party's witness or expert. The

<PAGE>

arbitrator's decision and award shall be made and delivered within six (6)
months of the selection of the arbitrator. The arbitrator's decision shall set
forth a reasoned basis for any award of damages or finding of liability. The
arbitrator shall not have power to award damages in excess of actual
compensatory damages and shall not multiply actual damages or award punitive
damages or any other damages that are specifically excluded under this
Agreement, and each party hereby irrevocably waives any claim to such damages.

     (c) The parties covenant and agree that they will participate in the
arbitration in good faith. This Section 16 applies equally to requests for
temporary, preliminary or permanent injunctive relief, except that in the case
of temporary or preliminary injunctive relief any party may proceed in court
without prior arbitration for the limited purpose of avoiding immediate and
irreparable harm.

     (d) Each of the parties hereto (i) hereby irrevocably submits to the
jurisdiction of any United States District Court of competent jurisdiction for
the purpose of enforcing the award or decision in any such proceeding, (ii)
hereby waives, and agrees not to assert, by way of motion, as a defense, or
otherwise, in any such suit, action or proceeding, any claim that it is not
subject personally to the jurisdiction of the above-named courts, that its
property is exempt or immune from attachment or execution (except as protected
by applicable law), that the suit, action or proceeding is brought in an
inconvenient forum, that the venue of the suit, action or proceeding is improper
or that this Agreement or the subject matter hereof may not be enforced in or by
such court, and hereby waives and agrees not to seek any review by any court of
any other jurisdiction which may be called upon to grant an enforcement of the
judgment of any such court. Each of the parties hereto hereby consents to
service of process by registered mail at the address to which notices are to be

                                                                   Exhibit 10.31

          Summary of Equity Appreciation Rights Plan - H3C Technologies

On October 13, 2004, the Board of Directors (the "Board") of H3C Technologies
Co., Limited (formerly Huawei-3Com Co. Limited ), or H3C, established an Equity
Appreciation Rights Plan (the "EARP") for the purpose of attracting and
retaining high quality personnel by offering individual incentives linked to the
success of H3C. At the time the EARP was approved, H3C was a China-based joint
venture between Huawei Technologies, or Huawei, and 3Com Corporation, or 3Com.
On March 29, 2007, H3C became a wholly-owned subsidiary of 3Com when 3Com bought
the remaining 49% stake it did not then own in H3C from Huawei (the "Buyout").
The Board amended the EARP on October 21, 2005 and again on March 29, 2007. The
material terms of the EARP, as amended, are as follows:

     -    Eligibility. All employees (except assemblers) and consultants of H3C
          during calendar years 2004 through 2006 were eligible to participate
          in the EARP. Dr. Shusheng Zheng, a current executive officer of 3Com
          and the Chief Operating Officer of H3C, was eligible to participate in
          the EARP.

     -    Pool. There are two components to the EARP, which was intended to be a
          limited duration incentive. The first element was designed to reward
          H3C employees based on increases in the value of H3C from plan
          inception to the date on which one of the shareholders bought out the
          other (also known as a "liquidity event"). A liquidity event under the
          EARP occurred on March 29, 2007, as described above, due to the Buyout
          transaction. The second element was intended to reward employees for
          positive cash flow generation, or earnings before interest and taxes
          (also known as "EBIT"). More specifically, the funding pool for the
          EARP consists of 10% of the appreciated value of H3C at the time of
          liquidity (the "Liquidity Pool") plus 15% of accumulated EBIT for
          calendar years 2004 through 2006 (the "EBIT Pool"). The Liquidity Pool
          was calculated to be $155,996,920 and the EBIT Pool was calculated to
          be $27,557,416.

     -    Share Grants. Grants of shares in the Liquidity Pool were made to
          participants for calendar years 2004, 2005 and 2006. The EBIT Pool was
          allocated to participants in 2007 based upon the level of their
          participation in the Liquidity Pool. Both the Liquidity Pool and EBIT
          Pool shares were distributed under terms and procedures approved by
          the Board, which approved and ratified the share distribution on March
          29, 2007.

     -    Vesting/Liquidity Pool. The vesting schedule of the shares from the
          Liquidity Pool is as follows: the 2004 shares vested 75% on the date
          of the closing of the Buyout, March 29, 2007, and the remaining 25%
          will vest on the first anniversary; the 2005 shares vested 50% on
          March 29, 2007, and 25% will vest on each of the next two
          anniversaries; and the 2006 shares vested 25% on March 29, 2007, and
          25% will vest on each of the next three anniversaries. Vesting of EARP
          shares on the anniversaries of the Buyout, or Liquidity Event, is
          contingent upon the continued employment of the participant through
          such anniversary dates. However, certain key executives and managers,
          including Dr. Zheng, continue to vest in the EARP if they are no
          longer employed by H3C but

          if, and only if, they are terminated at the Company's election without
          a "Valid Reason," as that term is defined in their employment
          contracts.

     -    EBIT Pool. The EBIT Pool was payable after the close of calendar year
          2006.

     -    Reserve Pool. A portion of the Liquidity Pool was reserved for
          distribution prior to the initial payout of the EARP, subject to the
          approval of certain executives of 3Com (the "Reserve Pool"). The
          Reserve Pool vests on the same terms as the 2006 Liquidity Pool
          shares. 3Com's Chief Legal and Administrative Officer approved the
          Reserve Pool distribution recommendations of Dr. Zheng on April 20,
          2007, except for the Reserve Pool shares allotted to Dr. Zheng. On
          April 23, 2007 the Compensation Committee of the 3Com Board of
          Directors approved an award of shares in the Reserve Pool to Dr.
          Zheng.

The EBIT Pool was paid in substantial part to participants on April 19, 2007;
the Liquidity Event installments of the Liquidity Pool vested upon the closing
of the 3Com buyout of Huawei's interest in H3C on March 29, 2007, and were paid
in substantial part on May 31, 2007.
