Network Management

Cisco ONS 15454 SDH Product Overview, R3.4

September 2002

Network Management

The ONS 15454 SDH is compatible with several network management protocols,

such as Simple Network Management Protocol (SNMP), Proxy Address

Resolution Protocol (ARP), Open Shortest Path First (OSPF) protocol, and

Routing Information Protocol (RIP). If OSPF is not available, static routes can

also connect to ONS 15454 SDHs through routers. DCC tunneling is provided for

interoperability with other vendors’ equipment.

Simple Network Management Protocol

SNMP is an application-layer Internet Protocol (IP) that enables network devices

to exchange management information. Network administrators can manage

network performance, find and solve network problems, and plan for network

growth. The ONS 15454 SDH supports SNMP Version 1 (SNMPv1) and SNMP

Version 2c (SNMPv2c). SNMPv2c offers additional protocol operations.

The ONS 15454 SDH uses SNMP to communicate segments of the CTC information

model to network management systems, such as the Hewlitt-Packard OpenView

Network Node Manager (NNM) or Open Systems Interconnection (OSI) NetExpert.

SNMP conveysinformation required for node-levelinventory, fault, and performance

management of the ONS 15454SDH node, and for generic read-only management of

E-1, E-3, SDH, and Ethernet.

The ONS 15454 SDH incorporates SNMP remote monitoring (RMON) to allow

network operators to monitor the ONS 15454 SDH Ethernet cards. RMON

operates transparently with a network management application, but you can

provision RMON alarm thresholds with CTC.

Proxy ARP

Proxy ARP enables a LAN-connected gateway ONS 15454 SDH to automatically

handle ARP requests forremote non-LANONS 15454SDHs connected by a DCC

to the gateway ONS 15454 SDH. Proxy ARP requires no manual configuration in

CTC.

Proxy ARP has a single LAN-connected ONS 15454 SDH stand-in (proxy) for

remote ONS 15454 SDHs. If a device on the LAN sends an ARP request intended for

one of the DCC-connected ONS 15454 SDHs, the gateway ONS 15454 SDH returns

1 2 ... 31 32 33 34 35 36 37 38 39 40 41 ... 55 56
