Cisco IOS question 12.4(15)T7 on 1812 Router

Typically, that would be controlled by the router hardware level, and what the specific hardware supports, not each individual revision of IOS.

Cisco Feature Navigator (cisco.com/go/fn) isn't going to tell you # of VLANs, because that is a hardware level datum, not software.

The data sheet for the 18xx routers

I'd go with the data sheet, excepting possibly a bug in implementation inside the specific IOS revision you are asking about could accidently restrict it more than it should be.

Great...thanks for the quick response!!!

So basically this router should work with 4 VLAN's like my others routers that are identical except this one has T7 vs T5.

Thanks!

I would assume so, and would also assume that whatever said 3 may have been a typo, or somebody reading a poor printout and couldn't distinguish a 3 from an 8.

Thanks Much Doug!
