Simultaneous tcpdump capture for two different physical intf 1.1 and 1.2

1) Create vlan by associating interface like this

 

[root@localhost:Active] config tmsh create net vlan int interfaces add { 1.1 }

 

[root@localhost:Active] config tmsh create net vlan ext interfaces add { 1.2 }

 

 

2) Now you can verify tcpdump for traffic in both the vlans simultaneously like this

 

[root@localhost:Active] config tcpdump -ni /Common/int

 

tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

 

listening on /Common/int, link-type EN10MB (Ethernet), capture size 96 bytes

 

 

In another session,

 

[root@localhost:Active] config tcpdump -ni /Common/ext

 

tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

 

listening on /Common/ext, link-type EN10MB (Ethernet), capture size 96 bytes
