VLAN Config

Gordon Curry — Mon, 30 Mar 2009 09:43:19 GMT

Hi all,

I'm struggling with VLAN's again and need to find out where I'm going wrong.

I have a pair of 5406zl switches on which I want to create a VLAN for server iLO connections (see drawing). There is a DHCP scope on our DHCP server and the VLAN needs to be accessable from the local 192.168.78.x network and the 192.168.3.x network.

I've created VLAN199 on each switch with an ip address for each and set a secondary ip address on the Cisco router LAN interface of 192.168.199.254 but I can't get any connectivity.

-----------------------------------------------

Switch config's are;

Switch01:

trunk A15,B15,C15,D15,D21 Trk5 Trunk
ip default-gateway 192.168.78.1
snmp-server community "public" Unrestricted
snmp-server host 192.168.20.223 "public"
snmp-server host 192.168.3.203 "public"
vlan 1
name "DEFAULT_VLAN"
untagged A1-A14,A16-A24,B1,B13-B14,B16-B24,C1-C14,C16-C19,C21,C23,D1-D14,D16-D20,D22-D24,Trk5
ip address 192.168.78.230 255.255.255.0
no untagged B2-B12,C20,C22,C24
exit
vlan 3
name "MPLS"
untagged C20,C22,C24
no ip address
exit
vlan 199
name "iLO"
untagged B2-B12
ip helper-address 192.168.78.12
ip address 192.168.199.1 255.255.255.0
exit

-----------------------------------------------

Switch02:

trunk A15,B15,C15,D16,D22 Trk5 Trunk

ip default-gateway 192.168.78.1
snmp-server community "public" Unrestricted
snmp-server host 192.168.20.223 "public"
snmp-server host 192.168.3.203 "public"
vlan 1
name "DEFAULT_VLAN"
untagged A1-A14,A16-A24,B1-B14,B16-B24,C1,C13-C14,C16-C24,D1-D15,D17-D21,D23-D24,Trk5
ip address 192.168.78.231 255.255.255.0
no untagged C2-C12
exit
vlan 199
name "iLO"
untagged C2-C12
ip helper-address 192.168.78.12
ip address 192.168.199.2 255.255.255.0
exit

Thanks in advance for any help with this.

Regards

Gordon.

Hi cenk sasmaztin.

Thanks for the quick reply....

I'll try out the settings you suggest and post the results. Have to be done out of hours though, this is in production, so I won't get a chance until tonight.

Gordon.
