Comware

Hello all,

My name is Luke. I'm new to HP networking field, but have experience working with Cisco and Juniper gear.

I was wondering if you could help me to establish proper way of allowing new VLAN over LACP link between HP and Cisco stack. Please see below for details:

1. on HP end, I got the following production config:

interface Bridge-Aggregation3
port link-type trunk
undo port trunk permit vlan 1
port trunk permit vlan 30 to 31 60 70 80 900
link-aggregation mode dynamic

interface Ten-GigabitEthernet1/0/51
port link-mode bridge
port link-type trunk
undo port trunk permit vlan 1
port trunk permit vlan 30 to 31 60 70 80 900
port link-aggregation group 3

interface Ten-GigabitEthernet2/0/51
port link-mode bridge
port link-type trunk
undo port trunk permit vlan 1
port trunk permit vlan 30 to 31 60 70 80 900
port link-aggregation group 3

2. On Cisco end, I have the following:

interface TenGigabitEthernet1/1/1
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 30 to 31 60 70 80 900
switchport mode trunk
switchport nonegotiate
channel-protocol lacp
channel-group 2 mode active

interface TenGigabitEthernet2/1/1
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 30 to 31 60 70 80 900
switchport mode trunk
switchport nonegotiate
channel-protocol lacp
channel-group 2 mode active

interface Port-channel2
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 30 to 31 60 70 80 900
switchport mode trunk
switchport nonegotiate

This is production envirement. Now, i need to create a new VLAN and add allow it over the LACP link.

Could you please advice how this should be handled on HP switch?

My steps are as follows:

1. HP end - create new VLAN and SVI

system-view

vlan 700

interface Vlan-interface 700
ip address 10.25.25.1 255.255.255.0

Not sure how to add that VLAN to bridge aggregation? Is there a similar command to Cisco IOS:

SWITCHPORT TRUNK ALLOWED VLAN ADD

Also, does such change have impact on the bridge group itself?

2. Cisco end is rather easy for me:

(create new VLAN and add it to the port channel)

config t

vlan 700

INTERFACE Port-channel2
SWITCHPORT TRUNK ALLOWED VLAN ADD 700

Any help is appreciated.

luke

You seem to be on the right track.

Have you used this to refre to?

Hi

If you want to add a vlan to an interface you just have to add it like this:

 port trunk permit vlan 700

It will not overwrite the other vlans, it will simply be added. I dont think this will interrupt the link.

When you are not sure, you can test it on a down link.

Kind regards

Since VLAN(s) and Bridge-Aggregation group have been yet defined, have you tried (port trunk permit vlan as per HP 5820X&5800 Switch Series Layer 2 - LAN Switching Command Reference R18xx manual) something like:

<hpswitch> system-view
[hpswitch] interface bridge-aggregation 3
[hpswitch-Bridge-Aggregation3] port trunk permit vlan 30 31 60 70 80 700 900

or just:

<hpswitch> system-view
[hpswitch] interface bridge-aggregation 3
[hpswitch-Bridge-Aggregation3] port trunk permit vlan 700

remembering that:

• If you use the port trunk permit vlan command multiple times, the trunk port carries the set of VLANs specified by vlan-list in each execution.
• The configuration made in Layer 2 aggregate interface view applies to the aggregate interface and its aggregation member ports (your Ten-GigabitEthernet1/0/51 and Ten-GigabitEthernet2/0/51).

Thank you all for the support. Adding new VLAN to the trunk/LACP agg is as simple as mentioned above:

port trunk permit vlan 700

Indeed, the vlan will be added to the existing trunk with no impact on it.

I can also confirm there's no impact on the bridge-agg/port channel. It remains stable...still I'd recommend making change within the maintenance window.

Thanks again.

Hi,

How does this command know what trunk the VLAN should be added to?

If i have trk1 configured on the switch and want to add vlan 100 to that trunk what command could I use?

i.e 

port trunk trk1 permitt vlan 100

Im also confused on how to do the reverse, so add a trunk to an existing VLAN - is that the same thing?

Thanks for your help,

Andy
