  • 1.  HP 2910 - VLAN-routing

    Posted Jan 29, 2014 09:50 AM

    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     192.168.7.245  255.255.255.0   No
      PCClients            | Manual     192.168.1.245   255.255.255.0   No

     

     

    show config

    ip default-gateway 192.168.7.254
    ip routing
    vlan 1
       name "DEFAULT_VLAN"
       untagged 1-3,5,7,9-14,18,21,23-24
       ip address 192.168.78.245 255.255.255.0
       no untagged 4,6,8,15-17,19-20,22
       exit
    vlan 5
       name "PCClients"
       untagged 4,6,8,15-17,19-20,22
       ip address 192.168.1.245 255.255.255.0
       exit

     

    192.168.7.254 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?

     

    thx

    Howdy,
    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 0.0.0.0 route rather than the "ip default route" when I've got IP routing enabled - buts that's my OCD.

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

     

    u mean the static 0.0.0.0 route to the router (192.168.7.254) 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.......

    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 0.0.0.0 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 0.0.0.0 0.0.0.0 192.168.7.254"  as your default route instead.
