The T/R interface in the 4000 does not support full duplex. Can you ping
any other devices on that VLAN?

Does anybody have seen this problem:
Token Ring interface on 4000 in up/up state with assigned ip address but I
can't ping this ip address from the same box ie. router can't ping its own
interface.
Hardware: 4000 connected to the cisco 3920 TR switch with VLANs configured.
My guess: Incorrectly negotiated Full Duplex.
Any ideas?
