Does anyone know the command to add an arp entry on a core switch? Hi, Try with the following command. Arp ip.ip.ip.ip 0123.4567.89ab arpa. To add a static MAC address to the MAC address table, enter the following command. Static MAC Address Table Entry. Posted on March 14, 2014; by Rene Molenaar; in CCIE Routing & Switching, CCNP SWITCH, Switching; Normally your switch will automatically learn MAC addresses and fill its MAC address table (CAM table) by looking at the source MAC address of incoming frames and flooding frames if it doesn’t know where to forward the frame.

Mar 25, 2011 How to clear single ARP entry in cisco routers/switches Posted on March 25, 2011 by ruchi 1 Comment This tutorial will explain How to clear single ARP entry in cisco routers/switches.Some times newtwork engineers need to clear a single arp entry in cisco router/switch. A static Address Resolution Protocol (ARP) entry is a permanent entry in your ARP cache. A static ARP entry can be managed from a Cisco device or a Windows workstation. Even though it is rarely called for, you can add or delete an entry from your cache. One reason you may want to add static.

With the introduction of Exchange project, and the new e-mail system, there was a need to load balance Client Access Servers (CAS), and Hub Transport Servers (HTS) to serve the KFUPM community. The Load Balancer is done in software using the Microsoft NLB service.
The design requires the CAS and HTS to be load balanced, currently there are three (3) of each. The servers need to communicate with other vlan 140 servers for various reasons such as replications, authentications, etc.
The Consultant used NLB with Multicast-IGMP. This mode has its own disadvantages. It actually Map Unicast IP address to a Multicast Mac address within the ports. Microsoft TechNet has the NLB details. With this method, there is some work that needed to be done by the network engineers. Since the Servers were virtual, the required changes were not following the standard norms that can be applied for the physical servers. Referring to VMware Knowledge Base will highlight the changes required in Cisco Switches.
1-Change in ARP table associated the IP to the MAC address.
This was done in both distributions switched.
Conf t
arp 10.140.8.74 0100.5e7f.084a ARPA
arp 10.140.8.75 0100.5e7f.084b ARPA
2-Change in the MAC address table to associate the MAC with the interfaces
Access switch 1 (all ports connected to ESX host directly)
Download and install high priority and client updates, especially those related to hardware.4. Next, choose to Check for updates. Restart the device. Windows 10 should update automatically, but to check your update status, select Start Settings Update and Security Windows Update. Microsoft wireless 3050 mouse instructions. If you are using an earlier version of Windows, press Windows+ R, type Control Panel, and then select OK System and Security Windows Update.

As a conclusion, although we have done this work on all switches. This is really not the way. As a recommendation the NLB Design should be changed, since there a lot of manual entries that needed to be worked on the switch. Failures to do so might lead to an outage of service.
