DavidDu1130 · March 2022

Hi supporters,
I have two question:
Firstly, I am facing this too much on coreswitch XGS4600 when checking log 7 2022-03-20T20:42:13+07:00 IN switch: IP table collision : 192.168.x.x

Product Model:

XGS4600-32F

ZyNOS F/W Version:

V4.70(ABBI.2) | 12/17/2021

Could you tell me what should I do to fix this matter.

Secondly, I want to show algorithm crc32l on my zyxel XGS4600 and change it to crc32u . But I dont know which command that help to show. Could you guys help me to do?

Hi @DavidDu1130,

Welcome to Zyxel Community!

Please use the following command to display which hash you were using, like the figure below.

XGS4600# show running-config

Note: "crc32l" is the default hash, so it won't display in the running-config.

In addition, you may use the "help" command for other hash algorithm options:

XGS4600(config)# ip iptable hash help<br>
