Juniper SYSTEM BASICS - CONFIGURATION GUIDE V 11.1.X

Configuring SNMP Packet Size
The SNMP server must support a PDU with an upper limit of 484 bytes or greater.
There is no need to coordinate the maximum packet size across the entire network.
Many requests and responses tend to be smaller than the maximum value.
snmp-server packetsize
■ Use to set the SNMP server’s maximum packet size.
■ Increase this value to improve the efficiency of the GetBulk operation.
■ Example
host1(config)#snmp-server packetsize 1000
■ Use the no version to set the SNMP packet size to the default maximum size,
1500 bytes.
■ See snmp-server packetsize.
Configuring Memory Warning
You can set up the router to send memory warning messages when memory
utilization reaches a specified value.
memory
■ Use to configure memory warning parameters. You set a high memory utilization
value and an abated memory utilization value. When the system reaches the
high utilization value, it sends warning messages. When memory usage falls to
the abated utilization value, the system stops sending warning messages.
■ Example
host1(config)#memory warning 80 70
■ Use the no version to return to the default values, 85 for high utilization and 75
for abated memory utilization.
■ See memory.
Configuring Encoding Method
You can control how the router encodes the ifDescr and ifName objects in the SNMP
agent’s interface table and in the bulkstats application.
There are two choices of encoding schemes: an E Series router proprietary method
and a conventional industry method.
■ The proprietary method identifies each interface sublayer with its type.
■ The industry method bases the type information for each interface sublayer on
the lowest layer 1 or layer 2 interface type.
