EMP interface and routing

[larsen]

Hi I have a SO6900 where I would like to manage the switch over the EMP interface instead of a normal port, for out of band management purposes.

I seem to fail in terms of getting a connection from something outside the the local subnet of the EMP interface.

So my question is can you use the EMP port for out of band managment ? You should be able to do that imho since there is a command to see what emp-routes you have in the machine.
However there is no way to configure emp-routes as I see it.

I'm a bit of a alcatel lucent noob so please bare with me =)

Below is my current config.

Code: Select all

mac-retention admin-state enable
mac-retention dup-mac-trap admin-state enable
mac-retention timer 30

You can use the static-route command, but you can't specify a default route that goes through EMP.

That is what I have tried but nothing get's routed out from the interface since the routing table is empty.


show ip routes

+ = Equal cost multipath routes
Total 1 routes

Dest Address Gateway Addr Age Protocol
------------------+-------------------+----------+-----------
127.0.0.1/32 127.0.0.1 2d21h LOCAL

show ip emp-routes

+ = Equal cost multipath routes
Total 3 routes

Dest Address Subnet Mask Gateway Addr Age Protocol
------------------+-----------------+-----------------+---------+-----------
10.10.48.0 255.255.252.0 172.18.237.1 2d21h STATIC
172.0.0.0 255.240.0.0 172.18.237.1 2d21h STATIC
172.18.237.0 255.255.255.0 172.18.237.30 2d21h LOCAL

But I can't ping anything on the 10.10.48 network or the 172.0.0.0/12 network. The packet doesn't go thru.

Does your gateway receive the request?

I can telnet from the gateway ( another router ) to the EMP interface. I haven't on the router itself yet. But I plan on doing that if I can't get this to work soon.

Andreas,

For me your issue sounds like a routing issue. Please verify if the request to reach the client in 10.x segment gets received by that client and what happens to the response. If your client doesn't receive the request, there will obviously be no response.

You can use "debug ip packet start timeout 30" and then issue the ping attempt from your OS6900 to do initial troubleshooting. (The output on your console will automatically end after 30 seconds)
