C9300 - Trunked EtherChannel issues

lucy.bettison · ‎11-03-2022

Hi,

Currently trying to configure two HP C7000 Chassis ports bundled into one EtherChannel, trunking multiple VLANs on a Cat9300

When we configure the interfaces with channel-group 10 mode on, both links come up bundled into the port channel but the hosts on the VM side are inaccessible.

When we configure the interfaces with channel-group 10 mode active, one interfaces goes suspended and one stays up and bundled.

The HP config is very basic and only used VLAN tagging and the LACP seems to be set and the timer set to short.

Can you post the config of both the side : ( is the VM confiured different port-channel, post that config)

when you say VM not reachable that VLAN to be allowed in the Port-channel ? it would be nice to have small diagram how they connected also.

last time i was success with below config :

Catalyst 9300

interface Port-channeX
switchport mode trunk

interface GigabitEthernet1/0/1
switchport mode trunk
channel-group X mode active

interface GigabitEthernet2/0/1
switchport mode trunk
channel-group X mode active

HP Switch

interface Bridge-AggregationX
port link-type trunk
link-aggregation mode dynamic

interface GigabitEthernet2/0/1
port link-type trunk
port link-aggregation group X

interface GigabitEthernet1/0/1
port link-type trunk
port link-aggregation group X

Hi BB

This is the config:

interface TenGigabitEthernet1/1/7
description to HP c7000 Host
switchport trunk native vlan 1000
switchport trunk allowed vlan 1300,1301,1305,1308,2300,2301,2305,2308
switchport mode trunk
channel-group 10 mode active
lacp rate fast
end

interface TenGigabitEthernet2/1/7
description to HP c7000 Host
switchport trunk native vlan 1000
switchport trunk allowed vlan 1300,1301,1305,1308,2300,2301,2305,2308
switchport mode trunk
channel-group 10 mode active
end

interface Port-channel10
description to HP c7000 Host
switchport trunk native vlan 1000
switchport trunk allowed vlan 1300,1301,1305,1308,2300,2301,2305,2308
switchport mode trunk
end

There isn't a vswitch at the other side, they just use shared uplink sets.

balaji.bandi · ‎11-03-2022

can you post the below output :

show etherchannel 10 summary

show interface Ten1/1/7

show interface Ten2/1/7

have you configured the other side HP blade chassis ? Another option trying a single-port trunk and see if that works.

There is no config on the HP side. They just tag VLANs.

interface TenGigabitEthernet1/1/7
description to HP c7000 Host
switchport trunk native vlan 1000
switchport trunk allowed vlan 1300,1301,1305,1308,2300,2301,2305,2308
switchport mode trunk
channel-group 10 mode active
lacp rate fast
end

switchport mode trunk
channel-group 10 mode active
lacp rate fast
end

Hello,

Looks like one port is using fast hellos while the other is using slow hellos. Since the one using fast hellos is up.bundled in prt channel try to make them all the same. They must all be either fast or slow (both sides) in order to be up in the port-channel and function correctly

interface x/x
lacp rate fast

Hope that helps

-David

In the config you provided after this it shows you only put that command on one interface. I would remove it form all. Secondly, try removing all config from the interfaces and leave the port channel config only. The ports should inherit the configuration. So shut down the ports, remove all config except the port channel config, then configure the port channel with all the settings (trunk, allowed VLAN, native VLAN, etc) See if that brings it up.

lucy.bettison · ‎11-07-2022

That put both ports into suspended. They don't inherit all the settings.

And having LACP rate fast on both interfaces still causes one to go suspended.

As I guess, the partner use different Dev-ID in both Link and that prevent port to bundle,
so check HP side, are you connect cisco to two HP SW ?
