SG300 - Error No More IP addresses could be added

[dmackerracher]

Hi, 

I'm trying to add an additional vlan on to an SG300. I've created the vlan, but when I try and assign the vlan interface a static IP, I get an error message 'No more IP addresses could be added'.

I get that error from both CLI and GUI. Currently, there are only 2 other vlan's, and I have a test SG300 that has more vlan's and IP addresses for interfaces assigned.

Any idea what's going on?

Here's the relevant section from the config:

interface vlan 1
 ip address 192.168.1.32 255.255.255.0
 no ip address dhcp
!
interface vlan 10
 name Main
 ip address 192.168.42.254 255.255.255.0
 ip dhcp relay enable
!
interface vlan 20
 name "Building 3"
 ip address 192.168.45.254 255.255.255.0
 ip dhcp relay enable
!
interface vlan 30
 name "Building 2"
!

It's vlan 30 I can't add the IP address to.

Cheers, 

Donald.

Such Error is due TCAM utilization is exhausted.  IPv4 routing in use should be less than Maximum value. By default it is 128 entries. The new interface will exceed the count therefore it is not allowed. 

Solution: either increase the TCAM value through resource utilization table or remove unwanted VLAN Interface which is not in use.
