Virtual bridging
In earlier releases, the
bridges relationship was between MACs and the switch port. The port
bridges MAC relationship is made regardless of the type of the MAC,
physical or virtual. This resulted in a connection creation issue
for the Hosts with ESX Server installed connected to a switch and
routers with HSRP/VRRP configured connected to the switch.
In
this release, Port instead of Bridges forms a new relationship called
VirtualBridges with virtual MACs. During discovery, if a switch port
is associated with a MAC address that matches the VirtualMACPattern
configured in the tpmgr_param.conf file, a VirtualBridges relationship
is created for the switch port. The VirtualBridges relation is also
formed for Systemless MAC irrespective of the VirtualMACPattern.
Systemless MAC will have virtualbridges relationship with the port.
The default VirtualMACPattern has the VMware specific MACs, VRRP,
and HSRP MACs. By removing the VirtualMACPattern from the tpmgr-param.conf
file, the Bridges relationship gets established.
