N7K# show system internal pixm info ltl 0x1f

Type            LTL

−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−

With this output, you can verify that Orion instance 8 (the FE that makes the forwarding decision for
Eth3/18) has a hardware MAC address entry of 0x1f for the destination MAC address 0050.56a1.1aef. This
index is also the destination LTL (di) within the F1 ELAM data. 

Additionally, you can verify that LTL 0x1f maps to port Eth3/26. This confirms that the frame is sent from
port Eth3/26.

In order to verify how the switch allocates the LTL pool, enter the show system internal pixm info ltl−region
command. The output from this command is useful in order to understand the purpose of an LTL if it is not
matched to a physical port. A good example of this is a Drop LTL:

N7K# show system internal pixm info ltl 0x11a0

0x11a0 is not configured

N7K# show system internal pixm info ltl−region
