inter vlan routing 3com 4500 switch

Hi!

 

Not working inter vlan routing in my 3com 4500 switch.

I have two vlan in my 3com 4500:

VLAN 1: 192.168.44.51/24

192.168.44.51 - it's ip on my 4500 switch

VLAN 2: 192.168.45.1/27

 

I configured port 21 in VLAN 2, type access and connect him notebook, gateway on network interface in the notebook 192.168.45.1, ip address 192.168.45.2

 

Routing automatically created:

[switch01]disp ip routing-table
 Routing Table: public net
Destination/Mask   Protocol Pre  Cost        Nexthop         Interface
127.0.0.0/8        DIRECT   0    0           127.0.0.1       InLoopBack0

192.168.45.1/32    DIRECT   0    0           127.0.0.1       InLoopBack0

 

But ping between VLAN 1 and VLAN 2 not worked:

[switch01]ping -a 192.168.44.51 -i vlan-interface 2 192.168.45.2
  PING 192.168.45.2: 56  data bytes, press CTRL_C to break

From notebook with ip 192.168.45.2 (vlan 2) pinging only 192.168.45.1, but 192.168.44.51 (vlan 1), 192.168.44.1 - not (any computer from network 192.168.44.0/24 not pinging).

Re: inter vlan routing 3com 4500 switch

Problem solved.

The basic problem was in that that routing doesn't work between vlan 1 (default vlan) and any others vlan's.

And check firewalls on your PC :))

Re: inter vlan routing 3com 4500 switch

How did you solve the problem? Can you provide details?

 

I am having a similar issue. However, I have a third vlan (VLAN 999) that works OK while the other (VLAN 600) does not.

 

VLAN 999 is working but VLAN 600 is not. The setup is exactly the same and the routing table looks the same for both:

Re: inter vlan routing 3com 4500 switch

Just a follow up.

 

VLAN 600 never shows up in the arp table. I do not have any locally connected clients in that VLAN, so maybe that is OK. I do have clients connected down the line. ports 25 and 26 which are tagged for VLAN 600 (and VLAN 999 as well) are connected to 3COM 2928 SFP Plus and 3COM 2916 SFP Plus swicthes (ports for the fiber connections tagged for VLANs 999 and 600) downstream. Phone using VONA 999 work on the downstream switches but not clients connected to the 600 VLAN.

 

This should work. Very frustrating. I find these switches limited and frustrating. I'm used to Cisco switches.
