Alcatel Unleashed

Hi,

I want to trunk a New alcaltel switch (omniswitch 6850 u24x) to an exisiting cisco edge switch(Catalyst 2960-48).I would be trunking through a cross over cable.when connecting this new alcatel switch to the exisiting cisco edge switch what configuration changes needs to be done on the alcatel switch to make the trunking work?The cisco switch is configured for pvst and vtp mode transparent.so advice on what changes needs to be done on alcatel switch to make this trunking work.Further what is the respective commands on alcatel for configuring for pvst and vtp mode transparent.

Further what is the command for clearing config on a alcatel switch?

Thanks.

hello

browse the forum , you will find all info.

Hi,

forgive my Cisco config skills, its been a while (years). Anyway, lets say that you want to trunk VLANS 700 and 701

On the Cisco switch you may have a config similar to this I guess:

spanning-tree mode rapid-pvst

switchport trunk allowed vlan 700,701
switchport mode trunk
On the Alcatel Switch

vlan 700 enable name "test-700" (Create the vlan, enable it and name it)
vlan 700 enable name "test-701" (Create the vlan, enable it and name it)
bridge mode 1x1 (sets per vlan spanning tree)
vlan 1 port default 1/1 (this sets vlan 1 as the default vlan in the trunk which will be on port 1/1)
vlan 700 802.1q 1/1 (this sets vlan 700 as one of the 802.1q tagged vlans, this will recieve the tagged 700 from cisco)
vlan 701 802.1q 1/1 (this sets vlan 701 as one of the 802.1q tagged vlans, this will recieve the tagged 701 from cisco)

If you have no use for passing and recieving untagged frames in the trunk it my be worth disabling vlan 1

vlan 1 disable
You may also wish to disable spanning tree on this VLAN too if you use it as the default vlan in all trunks.
vlan 1 1x1 stp disable flat stp disable

For additional info, I am not 100% sure if there is a corresponding command on the Alcatel for the Cisco write erase command. Essentially you need to remove the boot.cfg file from both the working and certified directories, these are the configuration files written to memory. Just do a dir command to see the file system.

I hope this offers some help although I am not sure it answers all your questions.

AFAIK VLAN 1 is used for transmitting several Protocols on cisco switches (cdp/stp ?) so i would avoid disabling it if you are not sure if this is a problem.

I think vtp is not supported on Alcatel (cisco properitary) see http://old.alcatelunleashed.com/viewtop ... =52&t=7718 and there are alternatives as GVRP - but gvrp only runs on CATOS switches..

But as the cisco switch is vtp transparent, it is inactive and no need to configure an workaround on the alcatel.

if you look in alcatel doc search for pvst+

there is an explain how to use alu to cisco with pvst
