• HP recommends not enabling loop detection on TRILL ports, because TRILL networks prevent loops
from being generated. For more information about loopback detection, see Layer 2—LAN
Switching Configuration Guide.
• Do not configure the TPID for VLAN tags on RBs. For more information about TPIDs, see Layer 2
—
LAN Switching Configuration Guide.
• Do not connect multiple TRILL ports on an RB to the same link. Otherwise, these TRILL ports might be
elected as the AVFs of a VLAN at the same time because these TRILL ports cannot sense each other.
This will cause loops in the VLAN.

Enabling TRILL
After you enable TRILL on a port, TRILL can operate correctly by using default settings. A port with TRILL
enabled is called a "TRILL port."
Configuration restrictions and guidelines
When you enable TRILL, follow these guidelines:
• To enable TRILL on a port, first enable TRILL globally.
• Enable or disable TRILL on all ports in a VLAN, so that the ports in a VLAN have the same TRILL
status (enabled or disabled).
• Do not enable both TRILL and EVB on a port. The allowed VLAN list of a TRILL-enabled port cannot
overlap with that of an EVB-enabled port. For more information about EVB, see EVB Configuration
Guide.
