LAN, Switching and Routing

[kgabo]

Hi all! Is it possible to creat Vlans between a cisco switch and a non cisco switch e.g Extrem switch.?

We need to exten a lan to a little lan that is running on an Extrem switch.We are using the 802.1q on the cisco switches.

[mattcalderon]

yes it is. Vlans are standard dot1q. The method of tagging frames with vlan ids is standard.

Hi Matt!

Thanx for the Url site. It does not help much as im a cisco guy. Maybe have a look at configs Xtreme and Cisco maybe you can sport the probelm. Pliz Pay attesion to Vlan133 n 134.

Im running EIGRP on my net and he is running OSPF.

Hi Kgabo

Can I ask if the Extreme switch is running purely as an L2 switch or has it been licensed to run as an L3 switch? I just ask because of the number of VLAN's configured on the Extreme.

Also can I ask what the configuration line "configure vr VR-Default add ports 1-50" is doing? I am not familiar with this.

Finally, if you want to have traffic from VALN 133 and VLAN 134 pass between the Extreme and the Cisco you will need to create a trunk port on the Extreme. I see from the configurations posted above that you have designated port Fast Ethernet 0/4 on the Cisco as a trunk and allowed VLAN 133 & 134 on this trunk.

Now on the Extreme, which ever port the Cisco will connect to, run the following (assuming Cisco linked ot port 24 on Extreme)

configure vlan 133 add port 24 tagged

configure vlan 134 add port 24 tagged

This would enable port 24 as a IEEE 802.1Q trunk with traffic for VLAN's 133 & 134 allowed across the trunk. Substitute port 24 for the port the Cisco connects to.

HTH
