3Com 5500G-EI Vlan routing problem

Im new on this portal, so please be patient with me :-)  
I have a 3Com 5500G-EI 48-Port switch, and I have a problem with routing between my VLANs.
I have 3 VLANs include default. I want to ping host form VLAN2 to VLAN3 and I have got "Requested time out" and tracert  finished on GW for VLAN2. So I cant reach any host from VLAN2 to VLAN3, and from VLAN3 to VLAN2 is it the same.

Any idea?

Hi @muru02

Month ago , i configured 3Com Layer 3 switch ( VLAN Routing ) simply you need to do the following :

1-Create VLANs ( VLAN1 , VLAN2 , VLAN3 )
2-Add IP address to VLAN interfaces
3-Make sure that PCs From VLAN2 Has ( As gateway ) interface VLAN2 , PCs From VLAN2 has ( as a gateway ) interface VLAN 2 ....and so on

For Example :
interface VLAN 2 : IP :
PC from the same VLAN 2 has this configuration
IP address : / subnet mask / default gateway :

Note : make sure that your switch doesn't have any Access List ( ACL ) that denied traffice from VLAN to another one

if your problem not solved Please replay me ASAP , to give you an advice ..

if you need more help about 3com Switch ( Routing ) go to 3com website ...and look for 3com knowledgebase

Good Luck
Agree, and don't forget to plug in at least 1 device in a vlan 1 port, in order to get vlan 1 up.
