The system can store entries for up to 20 unique MIB view records. In addition to the four default MIB
view records, you can create up to 16 unique MIB view records. After you delete the default view with
the
undo snmp-agent mib-view
command, you can create up to 20 unique MIB view records.
Be cautious with deleting the default MIB view. The operation blocks the access to any MIB object on
the device from NMSs that use the default view.
Examples
# Include the
mib-2
(OID 1.3.6.1) subtree in the
mibtest
view and exclude the
system
subtree from
this view.
<Sysname> system-view
[Sysname] snmp-agent sys-info version v1
[Sysname] snmp-agent mib-view included mibtest 1.3.6.1
[Sysname] snmp-agent mib-view excluded mibtest system
[Sysname] snmp-agent community read public mib-view mibtest
An SNMPv1 NMS in the
public
community can query the objects in the
mib-2
subtree but not any
object (for example, the
sysDescr
or
sysObjectID
node) in the
system
subtree.

snmp-agent packet max-size
Use
snmp-agent packet max-size
to set the maximum size (in bytes) of SNMP packets that the
SNMP agent can receive or send.
Use
undo snmp-agent packet max-size
to restore the default packet size.
Syntax

Default
The maximum size of SNMP packets that the SNMP agent can receive or send is 1500 bytes.
Views

Parameters
byte-count
: Sets the maximum size (in bytes) of SNMP packets that the SNMP agent can receive or
send. The value range is 484 to 17940.
Usage guidelines
If any device on the path to the NMS does not support packet fragmentation, limit the SNMP packet
size to prevent large-sized packets from being discarded. For most networks, the default value is
sufficient.
Examples
# Set the maximum SNMP packet size to 1024 bytes.
<Sysname> system-view
