Tail traffic in CLI?

L3 Networker

Is it possible to tail live traffic in the CLI while running a grep (or match) for specific things? I would find this extremely useful..

 

Thanks.

Hi @Gareth.Doyle

 

yes and no: there are several ways, depending on what you want to know, to look for/at sessions/session details, but there is no 'follow'' function to see one particular session

 

you can >show session all filter  to find all sessions matchingsomething specific (application, port, ip,..)

admin@MyFirewall> show session all filter 
+ application         Application name
+ count               count number of sessions only
+ destination         destination IP address
+ destination-port    Destination port
+ destination-user    Destination user
+ egress-interface    egress interface
+ from                From zone
+ hw-interface        hardware interface
+ ingress-interface   ingress interface
+ min-kb              minimum KB of byte count
+ nat                 If session is NAT
+ nat-rule            NAT rule name
+ pbf-rule            Policy-Based-Forwarding rule name
+ protocol            IP protocol value
+ qos-class           QoS class
+ qos-node-id         QoS node-id value
+ qos-rule            QoS rule name
+ rematch             rematch sessions
+ rule                Security rule name
+ source              source IP address
+ source-port         Source port
+ source-user         Source user
+ ssl-decrypt         session is decrypted
+ start-at            Show next 1K sessions
+ state               flow state
+ to                  To zone
+ tunnel-decap        session is outer tunnel with inspection enabled
+ tunnel-inspected    session is inside tunnel
+ type                flow type
  |                   Pipe through a command
  <Enter>             Finish input


or you can >show session id which will show you the stats of one specific session

 

admin@MyFirewall> show session id 26709
