Hello,

I do have two extreme switches 450a-48t interconected.

SW is summitX-12.6.2.10-patch1-3.xos version with ssh mod installed.

from one switch I can ping the other in the same Vlan.

But when I do ssh I receive next error:

SW-00.16 # ping 192.168.13.2
Ping(ICMP) 192.168.13.2: 4 packets, 8 data bytes, interval 1 second(s).

SW-00.17 #
SW-00.17 # ssh admin@192.168.13.2
ssh: connect to host 192.168.13.2 port 22: Network is unreachable

I do understand ssh is enabled in all ports:

enable ssh2 port 22 vr all



Could someone help me with this issue?

BR

ssh2 vr [i]

ssh2 user [u] vr [i]

(e.g. ssh2 user switchadmin vr vr-mgmt 192.168.1.1)

Hey Tomas

Are you using out of band network or are you doing this inband? Vr-mgmt is out if band.

I do think is in-band.

same Vlan tagged, with different ports interconnected by vrrp

I will explain myself better:

I am connected with ssh to switch 0, IP: 192.168.13.1.

In the other switch , 1, there is the same vlan but with IP 192.168.13.2.

Both vlans are trunk and interconnected.

I can reach with ping the other switch, and I would like to ssh the other switch, but I can't.

I can ssh from my computer the 192.168.13.2



thanks

ok then you are inband. Use the command but change vr-mgmt to vr-default and let us know what happens.

great glad it is working.

The vr-mgmt is only for the out of band ethernet port on the switch. It is a completely different data plan then vr-default which is used for all of the data forwarding of the ethernet ports.
