I’ve a few switches which might be trunked by way of a LAN cable from one other swap. I seen that these switches generally have a tough time to SSH into. I get the error: “Connection timed out”. After some time and some tries I can join simply high quality. I checked the logs (sh log) and do not actually see something useful.
I’ve the next set an all of the switches:
aaa new-model
aaa authentication login default native
aaa authorization exec default native
aaa authorization community default native
aaa session-id widespread
line vty 0 4
access-class VTY-ACL in vrf-also
exec-timeout 9 59
logging synchronous
transport enter ssh
transport output ssh
line vty 5 15
access-class VTY-ACL in vrf-also
exec-timeout 9 59
logging synchronous
no exec
transport enter none
transport output none
line vty 16 31
exec-timeout 9 59
no exec
transport enter none
transport output none
The switches are up with no interruption. I can console in high quality.
