收集网络几口信息(包括bond br)

这个脚本主要收集接口名称、状态、IP、绑定接口。

脚本如下

 

#!/bin/bash
#  By Nick.Ma

#ETH_MAX=$(cat /etc/udev/rules.d/70-persistent-net.rules | grep -v "^#" | grep -c "eth*")

ETH_NAME=$(cat /etc/udev/rules.d/70-persistent-net.rules | grep -v "^#" | awk -F "," '{print $8}' | cut -c 8-11 | grep -v "^$")
let IFACE_L_MAX=$(cat /etc/network/interfaces  | grep -v "^#" | grep -A 7 "^auto br" -c )-1
let IFACE_B_MAX=$(cat /etc/network/interfaces  | grep -v "^#" | grep -A 7 "^auto bond" -c )-1

echo -e "Name\tState\tAddress\t\tRelated-Iface"
for i in ${ETH_NAME}  #${IFACE_L_NAME}
  do
    IFACE_STATE=$(ip link | grep "$i" | awk -F "," '{print $3}' )
    IFACE_IP=$(cat /etc/network/interfaces  | sed '/iface '"$i"'/{n;s/address//p}' -n | grep -v "^$")
    echo -e "$i\t$IFACE_STATE\b$IFACE_IP"
done

for i in $( seq 0 $IFACE_L_MAX )
  do
    #IFACE_Br_NAME=$(ip link | grep br$i | awk -F "," '{print $3}')
    IFACE_Br_STATE=$(ip link | grep br$i | grep -v "vir" | awk -F "," '{print $3}' | grep -v "^$" )
    IFACE_Br_IP=$(cat /etc/network/interfaces  | grep -v "^#" | grep -A 7 "^auto br$i"  | awk '$1~/address/{print $2}')
    BR_R_IFACE=$(cat /etc/network/interfaces  | grep -v "^#" | grep -A 7 "^auto br$i" | awk '$1~/bridge_ports/{print $2" "$3}')
    echo -e "br$i\t$IFACE_Br_STATE\t$IFACE_Br_IP\t$BR_R_IFACE" 
done

for i in $( seq 0 $IFACE_B_MAX )
  do
    #IFACE_BOND_NAME=$(ip link | grep bond$i | awk -F "," '{print $3}')
    IFACE_BOND_STATE=$(ip link | grep bond$i | awk -F "," '{print $3}' | grep -v "^$" )
    IFACE_BOND_IP=$(cat /etc/network/interfaces  | grep -v "^#" | grep -A 7 "^auto bond$i"  | awk '$1~/address/{print $2}')
    BOND_R_IFACE=$(cat /etc/network/interfaces  | grep -v "^#" | grep -A 7 "^auto bond$i" | awk '$1~/post-up/{print $4" "$5}')
    if [ "$IFACE_BOND_STATE" == "UP" ] ; then
 echo -e "bond$i\t$IFACE_BOND_STATE\t$IFACE_BOND_IP\t$BOND_R_IFACE" 
    else
      echo -e "bond$i\t$IFACE_BOND_IP\t\t\t$BOND_R_IFACE" 
    fi
done

 

结果如下:

Name    State   Address         Related-Iface
eth1
eth2
eth3
eth0    UP      172.30.39.7
br0     UP      172.30.39.89    bond0
bond0                           eth2 eth3
