Interface stats script

[the_rock]

Hey guys,

This script provided full report on all interfaces statistics from expert mode. dos2unix + chmod needed.

Lab example:

[Expert@CP-GW:0]# ./cp_ifstats.sh
ERROR: choose -a or -i "iface1 iface2"
Usage:
cp_ifstats.sh [-a] [-i "eth0 bond0 vlan10"] [-n ITER] [-t SEC] [-q]

Options:
-a All non-loopback interfaces (auto-discover)
-i "list" Space-separated list of interfaces to inspect
-n ITER Number of iterations (default: 1)
-t SEC Interval seconds between iterations (default: 5)
-q Quiet (no colors)

Examples:
cp_ifstats.sh -a
cp_ifstats.sh -i "eth0 bond0" -n 5 -t 2
[Expert@CP-GW:0]# ./cp_ifstats.sh -a
