What is Virtual Ethernet/IEEE 802.3 interface

Unanswered Question
Mar 16th, 2009

In a 6513 core when i gave 'sh version'it shows the following

114 Virtual Ethernet/IEEE 802.3 interfaces

146 Gigabit Ethernet/IEEE 802.3 interfaces

here what does the 114 vitual ethernet interface mean ?. Could you please explain.

I have this problem too.

These will be the SVI (Switched Virtual Interfaces) you have configured on your switch ie

Interface Vlan 100

To see a list of them run the command :-

sh ip int | inc Vlan

How many vlan interfaces do you have configured on your switch ie. if you do a "sh ip interface brief | include Vlan" how many are there.

Hello Padma,

in this count of gigabit port are counted also the ports that connect a service module to the backplane

see for example

32 Virtual Ethernet/IEEE 802.3 interfaces

96 FastEthernet/IEEE 802.3 interfaces

36 Gigabit Ethernet/IEEE 802.3 interfaces

1 Ten Gigabit Ethernet/IEEE 802.3 interface

in this chassis I don't have any tengiga external port the tengiga is the port of ACE module to backplane

And I have only 24 external GE ports

3 8 8 port 1000mb ethernet WS-X6408-GBIC

7 16 SFM-capable 16 port 10/100/1000mb RJ45 WS-X6516-GE-TX

but I have 4 GE ports between CSM and backplane

and 6 GE ports between FWSM and backplane

262 Po262(SU) - Gi6/1(P) Gi6/2(P) Gi6/3(P) Gi6/4(P)

271 Po271(SU) - Gi2/1(P) Gi2/2(P) Gi2/3(P) Gi2/4(P)

Gi2/5(P) Gi2/6(P)

2 6 Firewall Module WS-SVC-FWM-1

6 4 SLB Application Processor Complex WS-X6066-SLB-APC

the number of Virtual Ethernet is that of the Vlan interface

in your case it should mean you have defined 114 SVI vlan L3 interfaces

Hope to help
