ASR1001 interface won't come UP

Stephane ARDHUIN · ‎02-04-2015

Hi,

I need some help with the connection between a ASR1001 and a Catalyst 2960G. The interface on the ASR won't come up, and I am pretty sure this is a configuration issue but I can't figure it out

At first, both interfaces wouldn't come up, but since I have set speed and duplex to 1000/full on both sides, the switch port is up/up but the router port is still down...

Switch configuration :

interface GigabitEthernet0/6
switchport trunk allowed vlan 425,605
switchport mode trunk
speed 1000
duplex full
no cdp enable
spanning-tree bpdufilter enable

Router configuration :

interface GigabitEthernet0/0/0
no ip address
ip access-group InFilter in
speed 1000
no negotiation auto
ip virtual-reassembly
!
interface GigabitEthernet0/0/0.425
encapsulation dot1Q 425
ip address x.x.x.x 255.255.255.0
no ip redirects
no ip unreachables
standby 221 ip x.x.x.x
standby 221 timers msec 250 msec 800
standby 221 priority 90
ip virtual-reassembly
!
interface GigabitEthernet0/0/0.605
encapsulation dot1Q 605
ip address x.x.x.x 255.255.255.224
no ip redirects
no ip unreachables
ip virtual-reassembly
!

Any thoughts, ideas, suggestions...

Is there a debug I could turn on to troubleshoot the L2 on the ASR ?

Hi,

Are these copper or fiber ports?

gigabit copper ports

Hi,

Did you manage to sort this issue out?

I've currently mocked up a lab environment with an ASR1001-X and a 2960S (10G).

I have a similar setup to yourself but am using 10G between interfaces connected via MM fibre.

Interestingly, i'm not seeing any connectivity either.

I'll upgrade the 2960 to 15. code to see if it makes any difference.

UPDATE: The ASR was set to auto. Setting the remote end to "non-negotiate" FIXED the issue.

you changed it to Auto ? or it was incorrectly set to auto ?

Sorry, we're getting ready to deploy 1001's soon, and I'm trying to see what I should expect, as I've no ideas what kind of anomalies I'll find between XE and XR.

So, did you leave the no negotiate auto on the ASR ?

If it was a fiber link on a 9006, I'd have said try negotiation auto on the ASR. Might be worth a try.

It was "only" a hardware problem on both SFPs (bad serie?!). I had them replaced and now everything works fine.
