VDX-6720 packet capture problems

I know this is an old switch, but some things are just agitating.

I have a port channel consisting of one port on each of two VDX-6720 switches in a VCS fabric.

sw0# show port-channel 10
 LACP Aggregator: Po 10 (vLAG)
 Aggregator type: Standard
 Ignore-split is enabled
  Member rbridges:
    rbridge-id: 12 (1)
    rbridge-id: 54 (1)
  Admin Key: 0010 - Oper Key 0010
  Partner System ID - 0x007f,64-64-9b-5e-55-00
  Partner Oper Key 0004
 Member ports on rbridge-id 12:
   Link: Te 12/0/3 (0xC18018002) sync: 1   *
 Member ports on rbridge-id 54:
   Link: Te 54/0/3 (0x3618018002) sync: 1

Data is dying somewhere between me and the other party.I created a MAC ACL:
sw0# show run mac
mac access-list standard test_01
 seq 10 permit any count

I go to apply it to an interface:
sw0(config-Port-channel-10)# mac access-group test_01 ?
 Possible completions:
 in Ingress direction
out Egress direction
sw0(config-Port-channel-10)# mac access-group test_01 out %%Error:Applying ACL in egress direction not supported.
I know the manual says:
The Brocade VDX 6710, VDX 6720, and VDX 6730 do not support the following:
• Egress ACLs
Then why let it tab-complete on a platform that doesn't support it?

Okay, so let's do an ingress-only capture.

sw0# capture packet interface
Possible completions:
  fortygigabitethernet     FortyGigabit Ethernet interface
  gigabitethernet          Gigabit Ethernet interface
  hundredgigabitethernet   HundredGigabit Ethernet interface
  tengigabitethernet       TenGigabit Ethernet interface
Okay, so I can't capture on the port-channel, which the manual does state can only be done on physical interfaces.

sw0(conf-if-te-12/0/3)# mac access-group test_01 in
%%Error: This interface is not configured to layer2 mode
So I can't packet capture on a port-channel, but I can't put ACLs on the individual ports in a port-channel. Let's do a packet capture on both interfaces in the port-channel.

sw0# capture packet interface tengigabitethernet 12/0/3
sw0# capture packet interface tengigabitethernet 54/0/3
% Error: Interface is not a memeber of this Rbridge

What do I do?

You will need to configure the same ACL on Rbridge 54 then apply this to tengigabitethernet 54/0/3 on that switch
