In case of an interface configured with both a rewrite and egress EFP filtering, where egress traffic is getting
dropped unexpectedly due to egress EFP filtering, the user must first ascertain which stage the drops occur.
Output drops counter displays the drops occurred due to egress EFP filtering in the “show interface” display
for that interface. Output drops counter is a summation of drops from multiple causes and not necessarily due
to egress EFP filtering.
Note
By using the ethernet egress-filter command, you can configure egress EFP filtering in either global or L2
subinterface mode:
• ethernet egress-filter strict configures Egress EFP Filtering inGlobal Configuration mode.
• ethernet egress-filter {strict | disabled} configures Egress EFP Filtering in L2 subinterface mode.
SUMMARY STEPS
1. configure
2. ethernet egress-filter strict
3. interface {GigabitEthernet | TenGigE | FastEthernet | Bundle-Ether} instance.subinterface
4. ethernet egress-filter {strict | disabled}
5. exit
DETAILED STEPS
Step 1 configure
Example:
RP/0/RSP0/CPU0:PE44_ASR-9010# config Thu Jun 4 07:50:02.660 PST
RP/0/RSP0/CPU0:PE44_ASR-9010(config)#
Enters Global Configuration mode.
Step 2 ethernet egress-filter strict
Example:
RP/0/RSP0/CPU0:PE44_ASR-9010(config)# ethernet egress-filter strict
Enables strict egress filtering on all subinterfaces on the device by default.
Step 3 interface {GigabitEthernet | TenGigE | FastEthernet | Bundle-Ether} instance.subinterface
Example:
RP/0/RSP0/CPU0:PE44_ASR-9010(config)# interface GigabitEthernet 0/1/0/1.1
RP/0/RSP0/CPU0:PE44_ASR-9010(config-subif)#
Creates an L2 subinterface.
