VLAN ESW-540

[albertmilia]

Hi,

I have a new switch ESW-540 24-port, I upgrade firmware to 2.1.19.

I build 2 VLAN for 2 networks: VLAN 2 and VLAN 3 . I don't use the default VLAN 1.

This is my configuration:

port e1 and e2 : ACCESS PORT on UNTTAGGED VLAN 2

port e3 and e4 : ACCESS PORT on UNTTAGGED VLAN 3

port e1,e2,e3,e4: EXCLUDED VLAN 1

port e24: TRUNK PORT with UNTAGGED VLAN 1 and TAGGED VLAN 2 and VLAN 3

Communication (ping) between e1 and e2 --> OK

Communication (ping) between e3 and e4 --> OK

Communication (ping) between e1,e2 and e24 --> NOK  :-(

Communication (ping) between e3,e4 and e24 --> NOK  :-(

Communication (ping) between e5,e6,e7,.... (VLAN1) and e24 --> OK

Communication (ping) between e5,e6,e7,.... (VLAN1) and VLAN2, VLAN3 --> NOK - It's correct.

Any special configuration on e24 trunk port ????

Can you help me ???

Thanks,

Hi Albert,

Bit concerned about your testing process.  You have proved that untagged switch ports in vlan 1 can communicate with e24.  that makes perfect sense.

What what are you using (connected on e24 )  to check for tagged packets egressing out of E24 from PCs connected on  vlan 2 and vlan 3.  This testing device you are using must be vlan aware.

The switch port 24 must be connected to a VLAN aware router or layer 3 switch  that is trunked for ;

vlan1 untagged

vlan2 and vlan3 tagged.

So that routing can occur between vlans.

Indeed you are right,

I configured the VLAN support in Router connected to e24 and entirely correct.

Thanks for your help.
