Configuring SNMP

NCS 1010 SNMP OTS MIB support

SNMP MIBS in the NCS 1010 platform support many controllers and parameters of different operational types which help in interacting with the rest of the system.

SNMP traps

An SNMP trap refers to a type of SNMP Protocol Data Unit (PDU). An agent is able to send an unrequested message to the manager to notify about any important event with an SNMP trap, unlike other PDU types.

• Traps can be sent on SNMP version-2 (V2) or version-3 (V3) authentication.

• In version-2 (V2C) of SNMP, community public and UDP port are defined by default as 162.

• In version-3 (V3), user, group authentication methods like md5 and des56 are used and the UDP port needs to be mentioned.

Configuration on nodes is listed here.

• Configuration of traps server as receiver: A trap server listens only to both the protocols SNMP V3 and SNMP V2. For V3 traps, server IP, userid and UDP port are needed as in this example.

  • snmp-server host 10.65.41.209 traps version 3 priv nocUser1 udp-port 163

  For V2 traps, server IP, protocol 2c , community public and UDP ports are needed, as in this example.

  • snmp-server host 64.104.134.47 traps version 2c public udp-port 12217

• Configuration of user for SNMP V3 authentication: Configure username with ID like nocUser1 and groups like nocGroup1 etc, followed by the authentication methods like md5 and privileged protocols like des56 followed by user and owner types as in this example.

  • snmp-server user nocUser1 nocGroup1 v3 auth md5 encrypted 0505090C145F4B1B48 priv des56 encrypted 082F434D3C0A000543 SystemOwner

• Configuration for SNMP V3 View: View includes the MIB starting point like given in this example.

  • snmp-server view nocView1 1.3 included

• Configuration for Community String: Community string is public with read, write permission and system owner privileges like given in this example.

  • snmp-server community public RW SystemOwner

• Configuration for SNMP V3 Group: Defines the group as name nocGroup1 with V3 protocol and privileges, notify view and view name as nocView1 and includes read and write operations similarly.

  • snmp-server group nocGroup1 v3 priv notify nocView1 read nocView1 write nocView1

• Configuration for Traps Requireing Customers Check: Syslog as traps is enabled.

  • snmp-server traps syslog

• Configuration for Inventory: For insert and remove and other control operations given in this example.

  • snmp-server traps fru-ctrl

• Configuration for Traps: For config change request use as this example.

  • snmp-server traps config

• Configuration for Entity Related Update: Use as given in this example.

  • snmp-server traps entity

• Configuration for System Up/Down Related Traps: Use this example.

  • snmp-server traps system

• Configuration for Preserving the Ifindex Over Reload: Use this example.

  • snmp-server ifindex persist

A few examples of SNMP traps are provided.

Note

From R7.9.1 release onwards the SNMP trap snmp-server traps alarm is available for use.

NCS 1010 SNMP OLS MIB support

From R7.10.1 onwards, SNMP support is enabled on the NCS 1010 platform for OLS. This Optical Line Control (OLC) MIB is introduced to support all OLC based applications in NCS 1010.

CISCO-OPTICAL-OLC-MIB with OID value of 1.3.6.1.4.1.9.9.1057.
