Cisco IOS question 12.4(15)T7 on 1812 Router

Can someone tell me where can I find out exactly which features this
IOS has?

I was told that 12.4(15)T7 can only support 3 VLAN's on an 1812
router, however this does not seem right for this level of router.

Thanks.

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
http://www.cisco.com/en/US/prod/coll...ata_Sheet.html
says that they all support 8 802.1Q VLANs. (And 4 WiFi encrypted VLANs)

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.
