Disclaimer - I work in a soup to nuts understaffed shop and support almost everything.. servers, storage, blade system, SQL server... I've been made into the network guy too and learning comware over the last year. I've been having fun with it for the most part.. building IRf stacks to replace Dell junk at our sites.
Anyway I've been trying to setup a static 10GE meshed (4 ports) trunk from our core IRF (7506's layer 3) to a couple 5500 HI 48p POE's (layer 2) in an IRF. I need to pass 3 vlan's across the trunk. I can't get the ports to select in the link-agg.
7506 config
interface Bridge-Aggregation5
description B2IDFIRF 10GE mesh
port link-type trunk
port trunk permit vlan 1 100 105 107
Port config for one of 4 ports
interface Ten-GigabitEthernet1/2/0/3
port link-mode bridge
description bagg5 lynb2idirf01 p53
port link-type trunk
port trunk permit vlan 1 100 105 107
port link-aggregation group 5
#
#
#
5500 config
interface Bridge-Aggregation 1
port link-type trunk
port trunk permit vlan 1 100 105 107
Port config for one of 4 ports
interface Ten-GigabitEthernet1/0/53
port link-mode bridge
port link-aggregation group1
dis link-aggregation verb
..
..
Aggregation Interface: Bridge-Aggregation5
Aggregation Mode: Static
Loadsharing Type: Shar
Port Status Priority Oper-Key
--------------------------------------------------------------------------------
XGE1/2/0/3 U 32768 4
XGE1/3/0/3 U 32768 4
XGE2/2/0/3 U 32768 4
XGE2/3/0/3 U 32768 4
Do I need to setup the bridge agg on the 5500 stack?
Thanks for any enlightenment
Ron

Re: Trunking between IRF stacks?
When you add ports to a BridgeAggregation group you should not configure the individual ports when adding them, since they will inherit the config of the BAGG.
I do it like this on our 5900 switches:
interface Bridge-Aggregation17
description Blade12_SW1
link-aggregation mode dynamic
link-aggregation load-sharing mode destination-ip
interface Ten-GigabitEthernet 2/0/26
description BA17_Member
port link-aggregation group 17
interface Ten-GigabitEthernet 4/0/26
description BA17_Member
port link-aggregation group 17
interface Bridge-Aggregation17
port link-type trunk
port trunk permit vlan xxx yyy zzz

Re: Trunking between IRF stacks?
Yeah I typically don't touch the interfaces other than to label them.
The part I'm confused with is whether I need baggs on each end? Do I need to permit vlans on the access layer bagg if so (the access layer is not aware of the vlans).
I've setup a lot of baggs with devices like HP Virtual Connect modules with LACP and they negotiate and work fine.. this switch to switch bagg is giving me fits.. I'm sure it is something simple I'm missing.

Re: Trunking between IRF stacks?
Hi, did you get this to work?
One thing you should look at is whether you are using dynamic mode on the bridge interfaces. Using the command:
link-aggregation mode dynamic

The bagg needs to be the same on both sides sans the description and bagg number as they dont affect anything.
Here is an example of how things turn out for me.
interface Bridge-Aggregation7
description To Switch Z
port link-type trunk
undo port trunk permit vlan 1
port trunk permit vlan y x
port trunk pvid vlan x
link-aggregation mode dynamic
interface Ten-GigabitEthernet1/2/1
description BAGG7
port link-type trunk
undo port trunk permit vlan 1
port trunk permit vlan y x
port trunk pvid vlan x
qos trust dscp
port link-aggregation group 7

That pesky 1st layer is always a killer.

Re: Trunking between IRF stacks?
Layer 1 is always the layer we take for granted and the one that is usually the biggest mess.
Once the fiber was working right the dynamic baggs worked like a charm!
