According to my switch monitoring tool, Oper state is down and Admin state is up for rtr.0.1.
But if I issue "show port" , "show ip interface" I can not see such an interface. How to get an idea about the relation between rtr interfaces and vlans ?

Hello Weda,

The best command to determine this is by using the command 'show mac type mgmt'

The rtr.0.1 is a virtual port representing a router interface in a VLAN.  If an interface is created on a VLAN the virtual rtr port will remain down until there is an active physical port that has been assigned to that VLAN.

We have changed how this work since this question was posted.  In the release notes for 8.61.08 you will find the following:
Modified the routing command “show interface” to have rtr.0.x in output instead of repeating vlan xxx and modified linkup/linkdown syslog to have ifName instead of unit/slot/port.
