1. mac 修改老化时间设置:mac address-table aging-time 0 vlan 32 2. 4507上面设置arp表不老化设置:interface vlan 32 、arp timeout 0 结果:循环pingvlan-32的所有终端IP,暂未发现离线情况,感谢解惑。 5 有帮助 回复 yangpiguan Level 1 发布时间 04-24-2024 11:36 PM 和我的现象很像,最终...
This article explains how to set the Address Resolution Protocol (ARP) table of a switch to frequently clear the expired Media Access Control (MAC) addresses from the ARP table. In addition, this article illustrates how to clear the ARP ta...
They can PING loopback, clients in the same 2950sx Switch (If in same IP subnet) and the Core switch IP. But it can not ping clients through the Coreswitch, and no traffic is transferred through the coreswitch to the PC. BUT, the PC is recieving correct ARP-...
The default ARP table aging time is 4 hours while the CAM holds the entries for only 5 minutes. The switch sends out a frame to all forwarding ports within the respective VLAN when the destination MAC address is aged out from the CAM table. You need a CAM aging timer greater or equal ...
