Hi,
I am setting up Netflow Monitor to monitor traffic levels on our bunch of XGS Firewalls and unfortunately Netflow reports the discovered interfaces as ifindex(x).
What i am trying to find out is the easiest way i can identify what port is being referenced for say, ifindex10.
Any help much appreciated.
Cheers.
Hi,
Thank you for reaching out to Sophos Community.
To check the ifindex, use the command "ip link show" from the advanced shell. If you need to, apply a filter using grep. In the example below, I am filtering the output by interface UP.
#ip link show | grep - E 'UP'
10: Port2@mv-pcimux0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue group 0x02 nfmark 0x8001 nfmark6 0 nettype 0x02 state LOWERLAYERDOWN mode DEFAULT group default qlen 1000
Filter by ifindex10
#ip link show | grep -E '10'
10: Port2@mv-pcimux0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue group 0x02 nfmark 0x8001 nfmark6 0 nettype 0x02 state LOWERLAYERDOWN mode DEFAULT group default qlen 1000
1: ifindex | Port #
