I'm having issues with defining a source interface for my SSH sessions.
We have a 3810M stack deployed in a datacenter where we have a management subnet that is not directly connected to our default route to get to the branch sites.
Here's a fictive IP plan that represents the situation:
VLAN | IP Config IP Address Subnet Mask Std Local-------------------- + ---------- --------------- --------------- ----------MGMT | Manual 10.20.20.254 255.255.255.0 No NoDATA | Manual 10.10.20.254 255.255.255.248 No No
ip route 0.0.0.0 0.0.0.0 10.10.20.253
10.10.20.253 is the ip address of the firewall.
When I try to SSH to a brach the switch uses the "Outgoing-interface" policy to select the SSH source address and thus chooses the wrong ip address. We have a firewall between the DC and branches that only allows SSH from the management subnet.
On first glance there seems to be no option in configuring the SSH source interface.
Is there a configuration option in a sub-config or something like that?
I would like to not make any changes to the firewall.
Thanks in advance guys!
when use the SSH client of the switch there is no option for select interface ?
I do not have a "source" option when trying to connect.
"ip source-interface telnet <interface>" also controls the SSH ip source address.
