i want to enable dhcp snooping for a vlan 70 but the switch displays an error like this:
FXS1600(config)#ip dhcp snooping vlan 70
Insufficient Resources. Unable to apply DHCP snooping on VLAN 70
my vlans are not contiguous
is not it possible me to apply dhcp snooping only for one vlan?
my vlans are 2, 10, 12, 30, 40, 50, 60 exc...
Solved! Go to Solution.

Have you enabled ACL-per-port-per-vlan before enabing DHCP Snooping?
To run DHCP snooping, you must first enable support for ACL filtering based on VLAN membership or VE port membership. To do so, enter the following commands at the Global CONFIG Level of the CLI.
Then enable the DHCP Snooping on the VLAN
Then enable the trusted port/s to the DHCP Server

190 ports is fine, there is no limit that I know of for VLAN memebership and I have done more then 190 ports in VLAN. It maybe a possible bug, check what version you are running (show ver) and check the lastest release note for that code stream.
If you have support then it may be quciker to call the TAC as this should just work.

i have no response from TAC. i solved this issue by myself:
firstly i have removed all the ports under vlan: vlan 70 --> no untagged eth ...
then i entered the command again: ip dhcp snooping vlan 70
and no error it is ok.
finally i untagged vlan to the ports. vlan 70 --> untagged eth ...
and it is ok ..
