EHWIC-D-8ESG-P dhcp

phoeneous

First time configuring a EHWIC-D-8ESG-P inside a 2901, can't get dhcp to hand out addresses to anything connected to the switchports. Data is vlan 10,voice is vlan 20. Any help is appreciated.

oops, forgot to put that in

Try popping the IP addresses on the SVIs instead. Also make sure that the VLANs were created @ L2. Those switch modules are notorious for not auto creating VLANS when you paste in the config.

Also it looks like you have the voice VLAN as the native VLAN.

phoeneous

And that's what I originally did at first but it didnt work. What I found out is that you have to create the vlan first, creating the vlan svi doesnt create the l2 vlan.
vlan database
vlan 10
name data
vlan 20
name voice
exit
int vlan 10
ip add ...
encap dot1q 10 nat
exit
int vlan 20
ip add ...
encap dot1q 20 nat
exit

Also, when assigning the switchports to their respective vlans, you cannot use the range command. You have to apply the config to each interface one at a time. This was also confirmed by cisco tac. I guess it is a bug.

Also also, when I set the native vlan for int vlan 10 to 10, and did the same for int vlan 20m it would remove it from 10. Also a bug?

pitviper

Yeah, those modules are a bit finicky.

You shouldn't need the encap command on the SVIs.

Check this out to - gotta love it!
