Hello guys,
i'm new to aruba cx and the 8235 switch.
I configured a VSX pair and connected it through a multichassis lag to my old 5406 Server distribution switch (there it is a classical aruba trunk).
What I am now wondering about is, that default vlan 1 (native vlan on upstream multichassis lag) does not work.
The VSX Switches do no see any of the Upstream MAC Address in vlan 1.
The tagged vlans are working fine.
I tried with mc lag13 to my server 5406 and with mc lag 15 to my core 5406.
Same behaviour.
VSX "pair":
vlan 1
vsx-sync
vlan 11
name Mgmt
vsx-sync
description Mgmt
vlan 998
name keepalive
vsx-sync
description keepalive
vlan 999
name Quarantaene
vsx-sync
vlan 2080
name Kaba
vsx-sync
description Kaba
interface lag 13 multi-chassis
no shutdown
description lag13_Access-2
no routing
vlan trunk native 1
vlan trunk allowed 11,23,2080
lacp mode active
exit

There's another strange thing:
with the show vlan id, the untagged native vlan 1 is not seen on Upstream lag13
the tagged vlans are shown correctly.
Interfaces with "vlan access 1" or the ISL lag1 with "vlan trunk native 1 tag" are shown.
8325-demo-01# sh vlan 1
VLAN Name Status Reason Type Interfaces
1 DEFAULT_VLAN_1 up ok default 1/1/3,1/1/5-1/1/12,1/1/14,

8325-demo-01# sh vlan 11

11 Mgmt up ok static lag1,lag13,lag15
Show spanning-tree includes the lag13 as the root port!:
8325-demo-01# sh spanning-tree vlan 1

lag13 Root Forwarding 2000 64 P2P 18 258327 14 26

--------------------------------------------------------------------
The Upstream Aruba 5406 Switch is configured as follows:
interface D3
name "8325-demo-02_1/1/13"
untagged vlan 1
trunk trk13 lacp
exit
interface D4
name "8325-demo-01_1/1/13"
untagged vlan 1
trunk trk13 lacp
exit
interface Trk13
tagged vlan 11,23,2080
untagged vlan 1
spanning-tree priority 4
exit
-------------------------------------------------------------------
I guess the commands "vlan trunk native 1" and "untagged vlan 1" should be the correct ones.
On Aruba 5406 Switch vlan 1 and vlan 11 contain multiple mac-address entries:
Access_2 RZ# sh mac-address vlan 1
Status and Counters - Address Table - VLAN 1
MAC Address Port
------------- --------
000379-03f762 A1
00096b-161b7c A1
00145e-6a49ea A1
...
Access_2 RZ# sh mac-address vlan 11
Status and Counters - Address Table - VLAN 11
MAC Address Port
------------- --------
001c7f-6936b8 A1
005056-90191f A1
005056-aa0359 A1
Any Idea why I did not see mac-addresses from vlan 1 on the VSX Switches?
Thanks and kind regards
