Now I've tried to change my laptops gateway from being the. The VM server is in the 10.1.1.0 subnet, and after the move, all devices in the 10.1.1.0 subnet can still see it.

Secondary ip addresses to primary ip addresses is like inter-vlan routing the PC with a secondary ip address needs to go through its default gateway even if all devices are in the same broadcast domain.
#VMWARE MAC ADDRESS IS WITHIN RESERVED UPDATE#
If the MAC address changes but the IP is still the same all devices that are not informed of the change will point to the old pair IPaddress, oldMAC and something must be done to update this info. If so you are facing an ARP problem and as explained by other collegues the VMware could help with a RARP message gratuitos ARP to update the ARP tables.įor example when the Active HSRP router changes the new active sends out a gratuitos ARP that allow lan switches to learn that the VIP and VIP mac addresses are now reachable from another port.īut in the case of HSRP (if not using standby use-bia) there is a virtual IP and a virtual MAC and no changes are needed in the ARP table only the CAM table (L2 only) You answered that the MAC address changes when moving the VMware instance I wanted to let you guys know in case you had other suggestions, but I'm about to call Cisco on this one it makes no sense. The mac address matches the vmware host, and it matches the arp entry in the switch. If I clear the arp table, everything works fine until it's moved over again. 1, I think I've effectively elimated it being a vmware problem, but more of a switch issue. If I statically assign my address to the same 10.1.1.0 subnet and attach to either the core or the edge switch, I can see the vmware server. I've also created a new vlan and added my laptop port to that vlan, and still the same thing. I can see the vmware server after doing this. If I have my laptop get an address from our dhcp server, it will pull an address in the 10.2.1.0 subnet. I've connected a laptop directly to the core switch. Here's more information as to what I have so far.

I have to clear arp for the vlan that it's associated to.ĭoes anyone have any experience in what to do with this? I'm not even sure how to go about troubleshooting this any further. It doesn't work to clear just the arp entry for the interfaces that are associated to the vmware server.
I tried to clear arp on my workstation using netsh, and it didn't make a difference UNTIL I cleared ARP on the switch, and then it works fine. I connected directly into the core from my workstation, and I couldn't ping it from a different VLAN, but I could ping it from the same subnet on a different server. I COULD ping from the edge switch that uplinks to the core.Īt first I thought it was because we had the subnet that we use for our workstations as a secondary address on VLAN1. I COULD ping the server name from the 3750, soooo kindof tells me that the switch knows where the server is and it's updated it's table.
Lost ping from my workstation to the server IP.
All ports that the hosts connect to are configured with portfast, so it's not a learning issue that I can see. The problem is that when we move VMs from one system to another, we can't ping them anymore until I clear the arp table. Each host has three NICs in them: one for service console, and two for failover. I have to clear arp all of the time on a 3750.
