linkloop fails

Pietro84 — Fri, 26 Mar 2010 10:04:58 GMT

Hello,
I have a cluster solution and I need to configure lan ports for both server with APA.

Lans are connected in 2 cisco switches (trunking) under VLANS.

The error I have:

bash-2.05b# linkloop -i 0 0x001E0B88A27A
Link connectivity to LAN station: 0x001E0B88A27A
error: get_msg2 getmsg failed, errno = 4
-- FAILED
frames sent : 1
frames received correctly : 0
reads that timed out : 1

This is the test from lan2 to lan6(bonding lan2).

No error for other lans:
bash-2.05b# linkloop -i 0 0x001E0B88A27A
Link connectivity to LAN station: 0x001E0B88A27A
-- OK

This is the test from lan0 to lan4 (bonding lan0)

I have no error in trunking because vlans have same configuration.

My hardware is:

I don't know anything about your configuration, but source and destination must be in the same subnet, because linkloop is not routeable or anything like that.

Hello,
I tried to connect lans directly port to port using a cable.

I see that ports on same card are OK.

Linkloop from Built-in and AB545-60001 are OK

Linkloop from AB545-60001 to AB290-60001 FAILS.

Use lanadmin -g to look at the port status. The description will indicate the negotiation state, and the speed line will show the speed of the link.
