Cisco Active Network Abstraction VNE Reference Guide, Version 3.6 SP1
OL-14763-02
In a multiple (D)RP environments there is an option to configure a virtual management interface and
assign an IP address to it, so that the device is reachable via the same IP address no matter which (D)RP
is active. In such an environment, each (D)RP has its own IP address but it is not used in order to access
the device.
In order to get the virtual IP address, login to the device and run the command show running-config
ipv4 virtual address as shown in the example:
DRP/0/3/CPU0:CRS-PE1#show running-config ipv4 virtual address
ipv4 virtual address 10.52.123.11 255.255.255.0
If the SDR is managed in-band the management IP address should be supplied by the customer.
The owner SDR (namely, the main router) presents all the modules that are installed on the chassis,
excluding the ports that belong to other SDRs.
The VNE of the SDR only displays the modules that are associated with the SDR in the Inventory
window of Cisco ANA NetworkVision, it does not display the fabric, fan and power supply (namely, the
shared modules).
Multichassis Support for CRS-1
Multichassis support is available in Cisco ANA for 16-slot CRS-1 devices. As shown in Figure 1, the
chassis functions purely as a container for the shelves, which are treated as individual chassis and are
numbered incrementally starting with 0.
