You should only enable the Direct Attach feature on ports that directly connect to a VM
server running VEPA software.
To enable or disable the direct attach feature on a port,
enter the command:
configure
port portreflective-relay [on | off]
To see if the direct attach feature (reflective-relay) is
enabled on a switch port, enter the command:
show ports information
detail
Note
When the Direct Attach feature is configured on a
port, the port number cannot be included in the port list for a static FDB entry. For
example, the Direct-Attach enabled port can be the only port number specified in a
static FDB entry, but it cannot be included in a port-list range for a static FDB
entry.
