CISCO-GPRS-L2RLY-MIB
AI MIB Summary
The CISCO-GPRS-L2RLY-MIB monitors and manages the L2RLY protocol interface statistics and link states between the T-node and D-node components of a split Cisco-Alcatel SGSN. It tracks packet forwarding counters, flow control status, and Fast Ethernet subnet failure detection metrics to ensure reliable service delivery within the GPRS core network.
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.

ciscoGprsL2rlyMIBThe 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. MODULE-IDENTITY .1.3.6.1.4.1.9.9.9993 |

cgprsL2rlyNoRespToKeepAliveMsgNotificationEnableThe object indicates whether the system produces the

cgprsL2rlyInterfaceTableThe table that lists the interfaces which l2rly is
using. Currently the table has just two and always two
entries. There is only one l2rly T or D unit on each router.
To ensure reliability and do load sharing, there
could be two fast ethernets among the l2rly units.
Thus each l2rly unit could interface with two fast ethernets.
At least one interface should be configured and working
in order for l2rly to work. SEQUENCE OF CgprsL2rlyInterfaceEntry .1.3.6.1.4.1.9.9.9993.1.1.8 |
