Hello
Few questions about Cisco 1941 Router.
1. Port failure.
Scheme:
Cisco 1941 Gi0/0 <-> Cisco 2950 Fa0/18
Cisco 1941 Gi0/1 <-> Cisco 2950 Fa0/22
Firmware:
Cisco 1941: c1900-universalk9-mz.SPA.150-1.M3.bin
Cisco 2950: c2950-i6q4l2-mz.121-22.EA13.bin
Problem:
Sometimes (it might happen every day or once a week) one or both ports are going down without any messages in logs. Just updown event.
I have tried to catch smth with debugging, but it was nothing that could help to solve the problem.
Speed and duplex are hardset on both sides. I have already changed the patchcords and ports on Cisco 2950.
Cisco 1941 port config:
interface GigabitEthernet0/0
no ip address
duplex full
speed 100
no cdp enable
!
end
Cisco 2950:
!
interface FastEthernet0/18
description Cisco1941 g0/0
switchport access vlan 2
switchport trunk allowed vlan 483
switchport mode trunk
speed 100
duplex full
no cdp enable
spanning-tree portfast
spanning-tree bpdufilter enable
spanning-tree bpduguard enable
end
Of course i have Gi0/0.483 on Cisco 1941.
2. ssh pubkey
Model:
Cisco 1941 router.
Problem:
ip ssh pubkey-chain acting strange
I'd like to login to my cisco router with ssh + public key (like authorized_keys in OpenSSH).
I've done this:
#sh run | section ssh
ip ssh version 2
ip ssh pubkey-chain
username tstssh
key-hash ssh-rsa A644F5FD61865AC3E1F947CA4C9F76B5
quit
transport input telnet ssh
transport input telnet ssh
The debug log is in the attachment.
Thanks in advance.
