CISCO-GPRS-L2RLY-MIB

The MIB Module for managing the General Packet Radio 
Service(GPRS) L2RLY related information on Servicing
GPRS Support Node(SGSN).
In GPRS network, a SGSN is typically implemented as
a single node; in cisco-Alcatel joint development,
it's split into Telecom part (T-node) and Datacom
part (D-node). T-nodes and D-nodes are connected
by two fast ethernets. A simple connectionless protocol
called L2RLY is used to provide service of forwarding
packet between T-unit and D-unit, flow control and
defending against the failure of a FE subnet.

Notifications/Traps

NameOIDDescription
cgprsL2rlyUnitJoinNotification

.1.3.6.1.4.1.9.9.9993.2.0.1
indicates that a new 'SGSN T-node' joins the service.
This happens when a new SGSN node restarts or the network
problem (fast ethernets among the units) recovers.
cgprsL2rlyNoRespToKeepAliveMsgNotification

.1.3.6.1.4.1.9.9.9993.2.0.2
indicates that the 'SGSN T-node' failed to respond to
the L2 Relay 'Keep Alive' message. The cgprsL2rlyUid variable identifies
the  'SGSN T-node' that failed to respond.
