Nexus 5596UP with Error: no free label

[Lutz Gruenewald]

Hello Support Team,


I've a Nexus-Pair, PID N5K-C5596UP,  with some Fex-Switches attached to it. We configure them to act as Vlan-Termination point with a total of 71 SVIs (Vlan-interfaces). To 62 of them we attached an ACL to the interface. As we tried to do the same with the 63th interface we saw this error:

%AFM-3-AFM_VERIFY_FAIL: Access control policy modification on vlan 1021 failed

%ACLMGR-3-ACLMGR_VERIFY_FAIL: Verify failed: no free label


We thought it could have been an NX-OS Bug (this one: CSCus09017) so we updated the OS from 7.0.5.N1.1 to 7.2.1.N1.1 (see below) but the error persisted.

kickstart: version 7.2(1)N1(1)
system:    version 7.2(1)N1(1)

Does someone has a tipp on how can I solve this problem?

Thanks in advanced!

Lutz

Same problem here:

Pair of N5548UP both with version 7.1(4)N1(1)

Created a new vlan + svi + acl for it.

on switch2 everything went normally

on switch1 (where pbr is enabled for testing) I could create the VLAN + SVI but not apply the ACL on it.

%AFM-3-AFM_VERIFY_FAIL: Access control policy modification on vlan 360 failed

%ACLMGR-3-ACLMGR_VERIFY_FAIL: Verify failed: no free label

PBR is currently enabled on no interface.

Total VLANs: 17

Thanks in advance,

Marcel
