Wired Intelligent Edge

Hello All,

I try to configure trunk from 2930F switch on two ports connected to HP switch (switch1). I can ping and login to 2930F from switch1 via management vlan. My problem is to ping 2930F from another HP switches connected to switch1. Trunks on all switches are configured in the same way.

On 2930F show arp vlan 100 shows no mac address for other switches (switch1 only).

After running ping from 2930F to other switches its (2930F's) mac address is visible on other routers.

What configuration directives should I check to allow packets from other switches to reach 2930F? Or what other issue couse my problem?

BR,

Michał Szamocki

Looking at relevant portion of published running configuration...it can be said that the Switch hasn't routing enabled (only D.G. is set) and logical interface Trk1 (made of ports 49 and 51) is just Untagged member of VLAN 1 and Tagged member of VLAN 90.

It's supposed that peer LAG/Trunk interface has the same VLAN IDs memberships. Isn't it?

Yes, it has, I mean on the switch on the other side of the trunk the trunk is added as untagged to vlan1 and as tagged to vlan 90.

You could provide outputs of these commands (and corresponding ones on the peer switch):

show lldp info remote-device

show lacp | include "Trk1 "

show trunk | include "Trk1 "

show vlan port trk1 detail

show spanning tree

This is the situation:

SWITCH1 and SWITCH2 see each other through trunk trk1:

SWITCH1(ports L1,L2=trk1)<===>SWITCH2(ports L1,L2=trk1)

SWITCH2 and SWITCH3 see each other through trunk named trk7 from SWITCH2 side and trk1 from SWITCH3 side:

SWITCH2(ports L7,L8=trk7)<===>SWITCH3(ports 49,51=trk1)

SWITCH1 does not see SWITCH3 (with SWITCH2 acting as man-in-the-middle). When I ping SWITCH1 from SWITCH3 I get timeout and SWITCH3 does not see SWITCH1 and does not have its MAC in ARP table, but ARP address of SWITCH3 appears in SWITCH1 arp table (!?!?).

Enclosed please find shortened configuration files of the three switches together with the results of the commands you asked for (the output is below the configuration dump in each file). Command "show lacp | include "Trk1 "" did not return anything on any of the switches.

Thank you very much for the questions and interest in our problem, parnassus!

On SWITCH2 trk7 L7+L8 was defined as dt-trunk, AKA Distributed-Trunk (Wrong!).

All remaining Port Trunks are of type "trunk" (thus static, non protocol). I strongly (strongly) suggest you to reconfigure all your Port Trunks (trk1, trk7, etc.) as LACP instead...that way Port Trunk will be defined as trunk X,Y trkZ lacp (and the show lacp will show you something...) instead of current trunk X,Y trkZ trunk.

parnassus, your advice worked perfectly, thank you very much!
