2 Vlans with Mobile tag enabled?

[Ragnarroeg88]

Hi everyone,

i am new at configure switches. i've got the task to combine 2 Voice-Vlans on one Alcatel 6450Switch.
My first idea was to set a second Vlan to Mobile-port.

vlan 100 enable name "IP-Phones"
vlan 200 enable name "Computers"
Vlan 200 port defaul 1/1-23
vlan 300 mobile-tag enable
vlan 300 port default 1/24


Vlan 301 enable name "IP-Phones_2"
Vlan 301 mobile-tag enable
Vlan 301 mac range 20:CC:27:4B:00:00 20:CC:27:4B:FF:FF

! LLDP :
lldp network-policy 1 application voice vlan 300 l2-priority 5 dscp 46
lldp chassis tlv management port-description enable system-name enable system-description enable
lldp chassis tlv management management-address enable
lldp chassis tlv med network-policy enable
lldp chassis med network-policy 1

Lldp network-policy 2 application voice vlan 301 l2-priority 5 dscp 46
lldp chassis tlv management port-description enable system-name enable system-description enable
lldp chassis tlv management management-address enable
lldp chassis tlv med network-policy enable
lldp chassis med network-policy 2

would that be working?

best regards
Ragnar

Thats a good idea with mobile tag for both voice vlan.
If you know the real ports for the phones you can use the following commands instead of "chassis"
lldp 1/1/1-12 med network-policy 1
lldp 1/1/13-23 med network-policy 2
So the attached phones learn the vlan 300 or 301.

If you don't know the used ports of the phones-1 and phones-2 you can use another solution WITHOUT lldp med (so all phones do not tag the vlan).
- ports mobile
- both vlans without mobile-tag
- two (or more) vlan-rules
Vlan 301 mac range 20:CC:27:4B:00:00 20:CC:27:4B:FF:FF
Vlan 300 mac range xx:xx:xx:00:00:00 xx:xx:xx:4B:FF:FF

Thank you for your answer.

is it still possibile to use "chassis" in both network policies or does it cause problems?

[silvio]

With chassis it works for all ports. So only one of the policies will work. You need to make for sure at ports 1-12 f.e. the first vendor and at the other ports the other vendor.

Okay thanks.

but my problem is, that the vlan 300 (old phones) is already configured. vlan 300 is mobile tag enabled and got the lldp policy 1 rules. and vlan port mobile is set to all ports.
so i dont know whats the better way to add the new phones which has to be in vlan 301.
i cant set vlan 301 tagged because all ports are configured as vlan port mobile, but if i tag the vlan 301 as port mobile, i have to know the ports, where the phones are or will be connected to and use the two lldp policy rules. right?

if i would set vlan 300 as no port mobile, i have to create a qos rule for both vlans (300 &301) and than i have to set both vlans tagged on all ports. all new phones would be in vlan 301 because of the mac-rule of vlan 301. but how to set the old phones the the vlan 300?

Happy new Year to everyone!

the problem is solved!

vlan 300 port default 1/10
vlan 301 802.1q 1/10 "tagged_calling"
vlan 301 mac range 20:cc:27:4b:00:00 20:cc:27:4b:ff:ff

qos trust ports
policy condition voiceVlanCond source vlan 301
policy action voiceVlanAct priority 5 dscp 46
policy rule voiceVlanRule condition voiceVlanCond action voiceVlanAct
qos apply
