HP 2910 - VLAN-routing

Hello all,


got a new HP2910, on which I created 2 vlans for testing:


show ip
  IP Routing : Enabled
  Default TTL     : 64  
  Arp Age         : 20 
  Domain Suffix   :                              
  DNS server      :                                        

  VLAN                 | IP Config  IP Address      Subnet Mask     Proxy ARP
  -------------------- + ---------- --------------- --------------- ---------
  DEFAULT_VLAN | Manual   No
  PCClients            | Manual   No



show config

ip default-gateway
ip routing
vlan 1
   name "DEFAULT_VLAN"
   untagged 1-3,5,7,9-14,18,21,23-24
   ip address
   no untagged 4,6,8,15-17,19-20,22
vlan 5
   name "PCClients"
   untagged 4,6,8,15-17,19-20,22
   ip address
   exit is IP from router.

dhcp-relay is activated, but clients from vlan5 do not get an IP!?

From the switch console I can ping clients in both vlans, but between the vlans a ping does not response.

Did I missed anything at the ports configuration?


Are there any options to configure an authorized dhcp-server ip?

Re: HP 2910 - VLAN-routing

Shouldn't yr VLAN 1 vlan interface be a .7 and not a .78 on the third octet?

I'd prefer to use a static route rather than the "ip default route" when I've got IP routing enabled - buts that's my OCD.
Hope that helps - please click "Thumbs up" for Kudos if it does

Re: HP 2910 - VLAN-routing

you are right, it is 192.168.7 - was a typing error by myself!


u mean the static route to the router ( rather than the default route/gateway?

why not use both simultaneously?



ok issue is almost cleared.

main problem is a false gateway  entry at the dhcp-clients although the dhcp has the correct value.......

Re: HP 2910 - VLAN-routing

If you are not enabling ip routing then you need the default gateway for the switch to communicate with monitoring/management devices outside of the subnet it sits in, but if you are enabling ip routing then adding a route makes more sense as this entry will be used over the "ip default-route" entry.  As Ian said, its an OCD thing really, but also it's good house keeping.

default-gateway is disgarded when you have "ip routing" enabled on the switch. You need to set "ip route"  as your default route instead.
