Wireless Access

I have a wx3024 AC, and I have configured vlan 1 with: 1.1.1.1/22(existing Network) and VLAN  2 interface 10.10.1.1/24 for wifi users.

On the switch connecting to the AC which is L3, have configured int VLAN 2(10.10.1.2/24), also configured a Gig interface port 1/0/2 as a trunk port permiting VLAN 2 with VLAN 1 as untagged and on the Wifi engine have also configured int GIG1/0/1 as a trunk port permittng VLAN 2 with untagged VLAN 1.

On another switch I have configure a Gig1/0/10 to acc vlan 2. Now from  L3 Switch I cannot ping 10.10.1.1/24

AC]int vlan 1

AC]ip add 1.1.1.1/22

AC]vlan 2

AC-int-vlan2]ip add 10.10.1.1/24

AC]int gig1/0/1

AC]port link-type trunk

AC]port trunk permit Vlan 2

AC]save..........

L3-switch-intvlan1]ip add 1.1.1.2/22

L3-switch-intvlan1]vlan 2

L3-Switch]int vlan 2

L3-Switch-intvlan2]ip add 10.10.1.2/24

L3-intgig1/0/10]port link-type trunk

L3-tntgig1/0/10]port trunk permit vlan 2

L3-intgig1/0/10]save.........

I cannot ping 10.10.1.1 from the L3-switch,and from the AC cannot ping 10.10.1.2/24. what could be the problem, Can only ping Vlan 1 addresses from both devices?

Your help will be highly appreciated.

Hi,

Did you check the config of the switch engine inside the AC ?

This is the switch which manages the external switch ports and the internal Gig switch port to the AC.

To verify, connect to the AC and use:

 oap connect slot 0

This will connect you on the console of the switch engine inside the AC.

On the switch, you can use the "dis brief int" so see all the ports.

You will see a port g1/0/29, this is an internal switch port which connects to the g1/0/1 of the AC.

So when you want vlan tags between the AC and the external network (e.g. on g1/0/1 of the switch), you need:

# define vlans on switch

vlan 2

# define external facing g1/0/1 as vlan tagged trunk:

int g1/0/1

 port link-type trunk

 port trunk permit vlan 2

# define internal AC facing g1/0/29 as vlan tagged trunk:

int g1/0/29

 port link-type trunk

 port trunk permit vlan 2

# verify

dis port trunk

# save config of switch (separate config from the AC!)

save

Hope this helps you,Peter.

it works, thanks much appreciated
