This command is used in Superqinq interface configuration mode of
switches. After the ARP proxy function between qinq interfaces is
disabled, users can use show running-config command to view
the information.
This example shows how to disable the ARP proxy function be-
tween QinQ interfaces.
ZXR10(config)#interface superqinq1
ZXR10(config-if)#inter-subqinq-routing disable
show running-config

invert txclock

It is used to allow inverting the Rx clock signals of the synchronous
serial port at the DTE side. Use the no command to prohibit in-
version.
Interface configuration

invert txclock

no invert txclock
Inversion of Rx clock signals is prohibited.
� In special cases, to eliminate the delay of half clock period on
the link, the Rx clock signals on the synchronous serial port of
the DTE can be inverted. This command is valid only for clock
signals provided by some special CSU/DSUDCEs. No inversion
shall be made for general application clock signals.
� The command is applied only to ZXR10GAR, ZXR10 ZSR.
This example describes how to invert the Rx clock signals of the
synchronous serial port on the DTE.
ZXR10(config)#interface serial_1/1
ZXR10(config-if)#invert txclock

ip arp inspect

Use this command to enable or disable the dynamic ARP detection
function of DHCP on QinQ or Superqinq interface.
Interface configuration and Superqinq interface configuration

ip arp inspect

no ip arp inspect
The dynamic ARP detection function of DHCP on QinQ or Superqinq
interface is disabled.
This command is used in interface configuration mode and Su-
perqinq interface configuration mode of switches. After the dy-
namic ARP detection function of DHCP is enabled, users can use
show running-config command to view the information.
