Hello everyone,
I'm trying to configure one of the ports of a relatively old 6224 to accept both tagged and untagged packets. Ideally a Linux workstation should be configured with a default IP address but if I chose to, I should be able to configure additional 802.1q interfaces (e.g. using "vconfig"). On a Cisco this is straightforward:
#swithport mode trunk
#switchport native vlan xx
I have attempted the equivalent for the 6224:
console(config-if-1/g11)#switchport mode general
console(config-if-1/g11)#switchport general allowed vlan add 299 untagged
console(config-if-1/g11)#switchport general allowed vlan add 242,269 tagged
console(config-if-1/g11)#switchport general allowed vlan remove 1
...at which point all looks OK
console#show interfaces switchport ethernet 1/g11
Port: 1/g11
VLAN Membership mode:General Mode
Operating parameters:
PVID: 1
Ingress Filtering: Enabled
Acceptable Frame Type: Admit All
Default Priority: 0
GVRP status:Disabled
Protected:Disabled
Port 1/g11 is member in:
VLAN Name Egress rule Type
---- --------------------------------- ----------- --------
242 Tagged Static
269 Tagged Static
299 Untagged Static
Static configuration:
PVID: 1
Ingress Filtering: Enabled
Acceptable Frame Type: Admit All
Port 1/g11 is statically configured to:
VLAN Name Egress rule
---- --------------------------------- -----------
242 Tagged
269 Tagged
299 Untagged
... except it doesn't work. I mean tagged packets from the Linux workstation will go through to the respective vlans but the "299 untagged" doesn't seem to have any effects: untagged packets never reach VLAN 299. :-o
Of course, setting the port "access vlan 299" works like a charm but that's not what I want.
Looking through the "6200 series manual" it would seem as if the trick should be possible with "trunk" mode also e.g. page 745 of the said manual reads:
Syntax
switchport trunk {allowed vlan vlan–list | native vlan vlan–id }
... but at leas on PCT6224 with the 3.3.11.1 firmware, that's not possible: switchport trunk can only be followed by "allowed" NOT by "native".
Any advice?
