AW: Re:Switch B3 - VLANs

[Flemmig Dennis]

Hi Rogerio,

it seems that this is missing on Switch_1 :

set vlan egress 101 ge.1.48 tagged
set vlan egress 102 ge.1.48 tagged

The output below shows that VLANs 101,102 are not allowed on ge.1.48!

Kind regards
Dennis

Hi Dennis,

I have tried your solution, but there are a problem.

I eliminate host D and I changed number of ports and vlan id, then I typed the commands below:

Port of Host A (switch 1 ge.1.7):
set port vlan ge.1.7 1 mod
set vlan egress 101 ge.1.7 untagged
set vlan egress 102 ge.1.7 untagged

Port of Host B (switch 1 ge.1.10):
set port vlan ge.1.10 101 mod
set vlan egress 1 ge.1.10 untagged

Port of Host C (switch 2 ge.1.24):
set port vlan ge.1.24 102 mod
set vlan egress 1 ge.1.24 untagged


Uplink ports (ge.1.48 on both switches):
set vlan egress 1 ge.1.48 tagged
set vlan egress 101 ge.1.48 tagged
set vlan egress 102 ge.1.48 tagged


After this configuration, if in host A I do a ping to B, I have a answer, it's right, but if I do a ping to host C, I have no asnwer, it's undesirable. What is wrong?


Follow "show vlan" of the switches 1 and 2.


Switch_1(su)->show vlan

[Strebler, Reinhard (SCC)]

BTW: You can have more than one Vlan on one port. Be aware of the difference between ingress and egress rule.
Untagged ingress is "PVID" (set port vlan ...). This in unique. There is exactly *one* untagged ingress vlan per port.
Untagged egress is "set vlan egress ...". There is no limitation regarding the number of egress vlans in IEEE802.1Q - neither untagged nor tagged. The basic question is: Does it make sense?

Kind regards
Reinhard

Your output seem that you've find a bug...
You can't have 2 vlans untagged on one port (ge.1.7) in one switch...
Normaly the switch schouldn't accept such a configuration.

Hi Dennis,

I have founded the problem. The configuration in switches are right.
The problem was in interface of host C. I corrected it and then all is OK.

Thank you.
