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 
[Sysname] snmp-agent packet max-size 1024 
snmp-agent port 
Use snmp-agent port to specify the UDP port for receiving SNMP packets. 
Use undo snmp-agent port to restore the default. 
Syntax 
snmp-agent port port-num 
undo snmp-agent port 
Default 
The device uses UDP port 161 for receiving SNMP packets. 
Views 
System view 
Predefined user roles 
network-admin 
Parameters 
port-num: Specifies the UDP port for receiving SNMP packets, in the range of 1 to 65535. The default 
is 161. 
Usage guidelines 
After changing the port number for receiving SNMP packets, reconnect the device by using the port 
number for SNMP get and set operations. 
To display UDP port information, use the display current-configuration command. 
Examples 
# Specify the UDP port for receiving SNMP packets as 5555. 
<Sysname> system-view 
[Sysname] snmp-agent port 5555 
# Restore the default UDP port. 
<Sysname> system-view 
[Sysname] undo snmp-agent port 
snmp-agent remote 
Use snmp-agent remote to set the SNMP engine ID for a remote SNMP entity. 
Use undo snmp-agent remote to delete a remote SNMP engine ID.
