CENTRAL FAX CENTER 

Af n ti 8 ,JuS 

Claim 1 has been amended to include the limitations of previous claim 8 and to 

properly introduce the abbreviation "ID". Claim 8 has been cancelled, and claims 9 and 12 

made dependent on claim 1. 

Claim 17 has been amended to include the limitations of previous claim 21. Claim 

21 has been cancelled, and claim 22 made dependent on claim 17. Claim 22 has also been 

am.ended to correct an antecedence issue. 

Claims 30-45 have been amended to replace "human-machine interface" with 

"'computer interface'', since the Examiner has stated that all hum.an-machine interfaces are 

computer interfaces. 

No new subject matter has been added, and the scope of the claims is no different 

from that of claims previously on file. 

The Examiner has objected to claims 8 and 30-45 as containing various specified 

informality errors. Claim 8 has been cancelled. Claims 30-45 have been amended to 

replace the term "hwnan-machine interface" with the term "computer interface", which the 

Examiner feels is more appropriate. 

The Examiner has objected to claims 1-45 under 35 U.S.C. §I02(e) as being 

anticipated by U.S. Patent 6,678,241 issued to Gai et al. 

Claim 1 includes the limitation of selecting a plurality of backbone VLAN trunks. 

This is a limitation not ·taught by Gai. In the reasons for rejection, the Examiner states that 

Gai teaches this limitation as the links 248 of Figure 2. In the Examiner's response to the 

Applicant's previous argument.s, the Examiner states that the switches 230-246 of Gai 

associate their respective trunk ports with the VLAN designations, citing column 7 lines 10-

15. However, as argued previously, the mere presence of the links 248 and the mere 

association of the trunk ports with VLAN designations does not teach selecting the links, 

especially in the context of a provisioning method. In order to teach this limitation of claim 

10

1, the Examiner must show where Gai teaches selecting one of the links as part of a . 

provisioning method. 

Claim 1 also includes the limitation of associating the backbone VLAN ID with 

each one of a plurality of stackable tronk ports. This is a limitation not taught by Gai. The 

Examiner states (with respect to previous claim 8) that Gai teaches associating the 

backbone VLAN ID with each one of a plurality of stackable trunk ports at colwnn 14 lines 

28-30 and FIG. 3 elements 302a-302c. However, these passages teach only association of a 

VLAN ID with a trunk port, and not with a stackable trunk port. The present invention, as 

claimed, is directed to a provisioning method whlch enables a number of possible actual 

VLANs beyond the usual 4096 limit. Backbone VLANs travel over backbone VLAN 

trunks, which are defined between stackable trunk ports on core routers. The qualification 

of the trunk ports in claim 1 as being stackable is important, as this allows VLANs to be 

stacke4 beyond the usual limit of 4096. The Applicant respectfully points out that the 

extension of the number of VLANs beyond 4096 is not intended to be explicitly claimed. 

but is merely <1n advantage of the invention realized by the explicit limitation of associating 

VLAN IDs with stackable trunk ports. lbis difference between claim 1 and Gai is 

important, as the advantages of the present invention enabled by claim 1 are not possible 

using the teachings of Gai. 

Claim 1 also includes the limitation that the selection and association of the 

backbone VLAN IDs with the backbone VLAN tnmks is undertaken irrespective of an in· 

use and a stand-by designation of the backbone VLAN trunks. This is a limitation not 

taught by Gai. The Examiner states that "each physical VLAN is designated as ACTIVE, 

STAND-BY, and UNUSABLE. This implies that the trunks in the physical VLANs 

associated with each logi,cal VLAN are undertaken irrespective of a one in-use and/or 

stand-by designation". As argued previously, this is actually contrary to the limitation of 

claim 1. Because each logical VLAN (which the Examiner has equated with a backbone 

VLAN by equating the ID RED with a backbone VLAN ID) of Gai deliberately has one

exactly one in-use physical VLAN and one or more stand-by physical VLANs to act as 

redundant VLANs should the active VLAN fail. 

Claims 2-7, 9-12, 15, arid 16 are dependent on claim 1 and include the same 

limitations discussed above. Because Gai does not teach each and every element of the 

claims, the Applicant respectfully submits that claims 1-7, 9-12, 15, and 16 are not 

anticipated by Oai. 

Claim J 7 includes the limitation of obtaining a plurality of backbone VLAN IDs 

associated with a corresponding plurality of provisioned backbone VLANs. This is a 

limitation not taught by Gai. In the reasons for rejection, the Examiner states that Gai 

teaches this limitation in Figure 5C as the values RED, BLUE, etc. However, as argued 

previously, the mere presence of the VLAN IDs does not teach obtaining the VLAN IDs, 

especially in the context of a provisioning method. In order to teach this limitation of claim 

17, the Examiner must show where Gai teaches obtaining backbone VLAN IDs associated 

with a corresponding plurality of provisioned backbone VL~s. 

Claim 17 also includes the limitation of associating the backbone VLAN ID with 

each one of a plurality of stackable trunk ports. This is a limitation not taught by Gai. The 

Examiner states (with respect to previous claim 21) that Gai teaches associating the 

backbone VLAN ID with each one of a plurality of stackable trunk ports at column 14 lines 

28-30 and FIO. 3 elements 302a-302c. However, these passages teach only association of a 

VLAN ID with a trunk port, and not with a stackable trunk port. The present invention, as 

claimed, is directed to a provisioning method which enables a number of possible actual 

VLANs beyond the usual 4096 J.4nit. Backbone VLANs travel over backbone VLAN 

trunks, which are defmed between stackable trunk ports on core routers. The qualification 

of the trunk ports in claim 17 as being stackable is important, as this allows VLANs to be. 

stacked beyond the usual limit of 4096. The Applicant respectfully points out that the 

extension of the number ofVLANs beyond 4096 is not intended to be explicitly claimed, 

but is merely an advantage of the invention realized by the explicit limitation of associating 

VLAN IDs with stackable trunk ports. This difference between claim 17 and Gai is

important, as the advantages of the present invention enabled by claim 17 a.re not possible 

using the teachings of Gai. 

Claim 17 also includes the limitation that the selection and association of the 

backbone VLAN IDs with the backbone VLAN trunk is undertaken irrespective of an inuse and a stand-by designation of the backbone VLAN trunks. This is a limitation not 

taught by Gai. Toe Examiner states that "each physical VLAN is designated as ACTIVE, 

STAND-BY, and UNUSABLE. This implies that the trunks in the physical VLANs 

associated with each logical VLAN are undertaken irrespective of a one in•use and/or 

stand-by designation". As argued previously, this is actually contrary to the limitation of 

claim 17. Because each logical VLAN (which the Examiner has equated with a backbone 

VLAN by equating the ID RED with a backbone VLAN ID) of Gai deliberately has one 

active physical VLAN associated with it and a number of stand-by physical VLANs, the 

association cannot be said to be irrespective of whether the trunk is in-use or stand-by. In 

fact, if Gai' s association was irrespective of whether the trunks were in-use or stand-by, 

then the method tau~t by Gai would not work because the entire point of Gai is to have 

exactly one in-use physical VLAN and one or more stand-by physical VLANs to act as 

redundant VLANs should the a~tive VLAN fail. 

Claims 18-20, 22 and 23 are dependent on claim 17 and include the same limitations 

discussed above. Because Gai does not teach each and every element of the claims, the 

Applicant respectfully submits that claims 17-20, 22, and 23 are not anticipated by GaL 

Claim 24 is directed to a method of provisioning a stackable trunk port. The 

Examiner has not shown where Gai teaches a method of provisioning a stackable trunk 

port. 

Claim 24 includes the limitation of obtaining a plurality of backbone VLAN IDs 

associated with a corresponding plurality of provisioned backbone VLANs. This is a 

limit:alion not taught by Gai. The Examiner states that Gai teaches this in Figure 5c as the 

IDs RED, BLUE, etc. However, as discussed above with reference to claim 17, the mere 

presence of IDs is not sufficient to show a step of obtaining the IDs, certainly not in the 

context of a method of provisioning.

Claim 2~ also includes the limitation of associating the plurality of backbone VLAN 

IDs with the stackable trunk port. This is a limitation not taught by Gai. The Examiner 

cites colUIDD 14 lines 28-30 and Figuie 3 of Gai as teaching this limitation. However, these 

passages do not teach association of backbone VLAN IDs with stackable trunk ports. The 

present invention, as claimed, is directed to a provisioning method which enables a mnnber 

ofpossible actual VLANs beyond the usual 4096 limit. Backbone VLANs travel over 

backbone VLAN tnmks, which are defined between stackable trunk ports on core routers. 

The qualification of the trunk ports in claim 24 as being stackable is import.ant, as this 

allows VLANs to be stacked beyond the usual limit of 4096. The Applicant respectfully 

points out that the extension of the number ofVLANs beyond 4096 is not intended to be 

explicitly claimed, but is merely an advantage of the invention realized by the explicit 

limitation of associating backbone VLAN IDs with stackable trunk ports. This 'diff':rence 

between claim 24 and Gai is import.ant, as the advantages of the present invention enabled 

by claim 24 are not possible using the teachings of Gai. 

Claim 24 also includes the limitation that the association of the plurality of 

backbone VLAN IDs with the stackable trunk port is undertaken irrespective of the in-use 

or stand-by designation of the stackable trunk port. However, as discussed above with 

reference to claims 1 and 17, Gai expressly talces into account whether a physical VLAN is 

active or stand-by in making the association, and is therefore the opposite of "irrespective". 

Claims 25-29 are dependent on claim 24 and include the same limitations discussed 

above. Since Gai does not teach each and every element of the claims, the Applicant 

respectfully submits that claims 24-29 are not anticipated by Gai 

Claim 3 0 is directed to a backbone VLAN provisioning computer machine interface. 

The limitations of the claims include selectors and activators for effecting specified actions. 

Toe.Examiner has not shown where Gai teaches such a computer interface. The Examiner 

has treated claim 30 the same as claim 1, but these are different categories of claims and 

comprise different limitations. For example, the Examiner a~resses the preamble of claim 

30 by stating that Gai discloses a method of provisioning a backbone VLAN in Figure 4. 

However, Figure 4 in no way discloses a computer interface as recited in claim 30. This

ignores a major aspect of the invention., which is a NMS interface with specified 

functionality buttons which simplifies provisioning of backbone VLANs. 

Claim 30 includes the limitation of a backbone VLAN ID selector for selecting a 

plurality of backbone VLAN IDs. As discussed above, Gai does not teach backbone VLAN 

IDs. In additio~ the Examiner has not shown where Gai teaches such a selector within a 

human-machine interlace. 

Claim 30 also includes the limitation of a backbone VLAN trunk selector for 

selecting a plurality of backbone VLAN trunks. As discussed above, Gai does not teach 

backbone VLAN trunks. In addition, the Examiner has not shown where Gai teaches such 

a selector within a human-machine interface. 

Claim 30 also includes the limitation of an activator for committing associations 

between the plurality of backbone VLAN IDs and the plurality of backbone VLAN trunks. 

As discussed above, Ga{ does not teach backbone VLAN IDs or backbone VLAN trunks. 

In addition, the Examiner has not shown where Gai teaches such an activato~ within a 

human-machine inted"ace. 

Claim 30 also includes the limitation that the associations between the plurality of 

backbone VLAN IDs and the plurality of backbone VLAN trunks is undertaken irrespective 

of the in-use or stand-by designation of the backbone VLAN trunks. Howev~r, as discussed 

above with reference to claims 1 and 17. Gai expressly takes into account whether a 

physical VLAN is active or stand-by in making the association, and is therefore the 

opposite of "irrespective". 

Claims 31-44 are dependent on claim 30 and include the same limitations discussed 

above. Claim 45 is directed to an NMS which includes the limitations of claim 30. Since 

Gai does not teach each and every element of the claims, the Applicant respectfully submits 

that claims 30-45 are not anticipated by Oai. 

The Examiner is kindly asked to consider the aspect of the invention reflected in 

claims 30-4S. namely the NMS interface whose inventive elements simplify provisioning of 

backbone VLANs. The Applicant made such a request in response to the previous Office 

Action, but the Examiner has again failed to address the specific elemenr.s of claims 30-45, 

. and has not addressed our previous arguments with respect to claims 30-45.
