Description

This article provides information on the sFlow Agent-ID enhancement on EX-Series

Symptoms

Prior to Junos release 10.2, sFlow agent-id was auto-configured on the EX-switch based on the IP addresses on the switch with highest priority given to management interface address (Vme/Me) followed by layer 3 (RVI) interface IP.

Solution


The following command is issued to hard-code the desired IP:

Switch@juniper # set protocols sflow ?

Possible completions:
<[Enter]>                              Execute this command
agent-id                               Sflow agent ip address
+ apply-groups                  Groups from which to inherit configuration data
+ apply-groups-except     Don't inherit configuration data from these groups 
> collector                           SFLOW collector configuration
> interfaces                        Enable SFLOW on this interface
polling-interval                   Interval between port statistics (0..3600 seconds)
sample-rate                       Sampling rate (100..1048576)
source-ip                            Sflow datagram source ip address
> traceoptions                   Trace options for SFLOW
|                                            Pipe through a command

Switch@juniper# set protocols sflow agent-id <ip-address>

Note:Junos release 10.2 onwards, agent-id can be hard-coded on the switch with the desired IP.
