Are you sure that after updating the driver the NIC team is still in place?
Having a dual homed Citrix server is a recipe for trouble.  Dual homed
Citrix servers are supported only in very specific configurations and is not
a Citrix recommended practice.  NIC teaming is fine, dual homing as separate
NICs is not.

Subject: RE: What IP has this MAC?

 


Bing in over my head, I must confess to not knowing Cisco IOS.  I did find
the MAC address in the Cisco Network Assasin.  This will help in the
future... 

Now, this brings up Problem #2: 

The machine in question is a Dell PE-1950 Citrix server.  It has two NICs.
When the server was built, only one of the NICs was used.  Later, the
Broadcom software was downloaded and installed, and the two NICs were teamed
for fail-over redundency. 

Both the Cisco Network Assasin and the "ping / arp -a" show that this NIC
has the IP address "10.1.2.47".  It is a static IP address and is in our
DATA VLAN. 

Wireshark shows that this NIC is sending gratuitous ARP packets and is
claiming the address "10.1.20.45" (DHCP and in the VOICE VLAN). 

Any hints on how to make a (Dell/Broadcom) NIC stop sending gratuitious ARP
packets? 

Thanks again...
