I'm having some trouble with establishing a trunk port between a Cisco 6513 and Cisco 4948.
Here is the config:
Cisco 6513
int gig 8/1
switchport
switchport encap dot1q
switchport mode trunk
switchport trunk allowed vlan 1
speed noneg
no shut
int vlan 1
description Mgmt VLAN
ip address 10.10.10.1 255.255.255.0
no shut
Cisco 4948
gig 1/48
switchport
switchport encap dot1q
switchport mode trunk
switchport trunk allowed vlan 1
speed noneg
no shut
int vlan 1
description Mgmt VLAN
ip address 10.10.10.2 255.255.255.0
no shut
Status:
1- Both Gige's are up/up
2- But can't ping each other
Cards on Cisco 6513:
slot:7 2 Supervisor Engine 720 (Active) WS-SUP720-3B
Slot:8 2 Supervisor Engine 720 (Hot) WS-SUP720-3B
I have Gig7/1 on Cisco 6513 and Gi1/47 on the Cisco 4948 up, as a routed port. I hate to touch these ports or else I loose connectivity to the Cisco 4948.

Manny,
Can you provide from both 6513 and 4948 switches the output of " show int gig8/1 switchport " and "show int gig1/48 switchport" , also output of "show interface gig8/1 trunk" , show int gig1/48 trunk from the 4948 .
you may need to use " switchport trunk encap dot1q" in the interfaces , unless switchport encap dot1q syntax is a typo or command was introduce in a ios version Im not aware of then is fine, but the output of above interface information as well as "show vtp status" from each switch would help to understand your l2 topology and give us some hints on what could be the issue on the interfaces
Regards

Hi,
Can I ask you something ? Isnt is that the port are working as switchports ( trunk mode ) and you are assigning Ip address on that switchport and trying to ping them. I think ones the port is in switching mode the ip address is assigned to the SVI and then you can access the switch using that SVI ip address. It is always the routed port that are assigned the ip address.
Let me know if my understanding of switchports and routed ports are wrong !! plz
Thanks

sorry ! misread it the first time , drunk i believe ... did not see the interface vlan config. can you post
1> sh ip route
2> sh spanning tree
3> Vlan database
Thanks

Something is not right. The 'sh run' shows interface g1/48 as 'shutdown', but the 'sh int g1/48' shows it up/up.
Can you verify that it isn't shutdown.
07-06-2010 09:21 AM
Can you also post the 'show interface trunk' output ?

I dont have much experience with the Cisco 6515, can Gig8/1 on the Cisco 6515 be on-standby since its the standy card? Card in slot 7 is active. I figured Gig8/1 can not be used, but I maybe wrong.
