Switching The Nm-Specific Interface Index Format - HP 5500 EI Series Configuration Manual

Step
6. Configure the SNMP
access right.
7. Configure the
maximum size (in
bytes) of SNMP
packets for the
SNMP agent.
8. Configure the DSCP
value for SNMP
responses.

Switching the NM-specific interface index format

A network management (NM)-specific ifindex identifies an interface and is provided by the SNMP
managed device to the NMS. A network management-specific ifindex takes one of the following two
formats:
16-bit NM-specific ifindex—The system dynamically assigns 16-bit NM-specific ifindex values to
•
uniquely identify its interfaces. The 16-bit NM-specific ifindex value starts from 1 and increments by
1.
32-bit NM-specific ifindex—A 32-bit NM-specific ifindex value comprises an Offset, Interface Type,
•
Slot ID, and Chassis ID, as shown in
Command
•
(Method 1) Create an SNMP community:
snmp-agent community { read | write }
community-name [ mib-view view-name ]
[ acl acl-number | acl ipv6
ipv6-acl-number ] *
•
(Method 2) Create an SNMP group, and
add a user to the SNMP group:
a. snmp-agent group { v1 | v2c }
group-name [ read-view read-view ]
[ write-view write-view ] [ notify-view
notify-view ] [ acl acl-number | acl ipv6
ipv6-acl-number ] *
b. snmp-agent usm-user { v1 | v2c }
user-name group-name [ acl
acl-number | acl ipv6
ipv6-acl-number ] *

Remarks
Use either method.
By default, no SNMP group
exists.
The username configured by
using method 2 is equivalent to
the community name
configured by using method 1,
and it must be the same as the
community name configured on
the NMS.
Optional.
By default, the SNMP agent can
receive and send the SNMP
packets up to 1500 bytes.
Optional.
By default, the DSCP value for
SNMP responses is 0.
