Equipment Management
The Cisco WAN Manager Equipment Manager provides the ability to perform equipment
management functions such as adding lines and ports on a Cisco MGX 8220 edge concentrator
shelf.

Alarm Reporting/Event Log
Cisco WAN Manager displays major and minor alarm status on its topology screen for all nodes in
a network. It also provides an event log with configurable filtering of the log events by node name,
start time, end time, alarm type, and user specified search string.

Software Updates
System software and software updates are supplied on magnetic tape or floppy disk. You can then
load the system software files onto the Cisco WAN Manager workstation where they can be
downloaded to a buffer memory in each node in the network in a background mode without
disturbing network operation. When the loading is complete for all nodes, you issue a command to
switch all nodes over to the new software. The previous software is preserved and can be recalled
at any time.

Backup
You can obtain all network configuration files from the network and store them on the Cisco WAN
Manager workstation for backup purposes. In the event of a system update or a node failure, you
can download the configuration files to one or all nodes for immediate system restoration.

Network Interfaces
Network interfaces connect the BPX switch to other BPX or IGX switches to form a wide-area network.
The BPX switch provides these trunk interfaces:
The BPX switch provides these trunk interfaces:
•
T3
•
E3
•
OC-3/STM-1
•
OC-12/STM-4
The T3 physical interface utilizes DS3 C-bit parity and the 53-byte ATM physical layer cell relay
transmission using the Physical Layer Convergence Protocol.
transmission using the Physical Layer Convergence Protocol.
The E3 physical interface uses G.804 for cell delineation and HDB3 line coding.
The BXM-622 cards support these physical interfaces:
•
SMF
•
SMFLR
The BPX switch supports network interfaces up to 622 Mbps and provides the architecture to support
higher broadband network interfaces as the need arises.
higher broadband network interfaces as the need arises.
Optional redundancy is on a one-to-one basis. The physical interface can operate either in a normal or
looped clock mode. As an option, the node synchronization can be obtained from the DS3 extracted
clock for any selected network trunk.
