Cisco Cisco Nexus 9332PQ Switch Release Notes

Cisco Nexus 9000 Series NX-OS Release Notes, Release 6.1(2)I3(5b) 
Guidelines and Limitations for Private VLANs 

 

TCAM resources are not shared when: 

Routed ACL (Access Control List) is applied to multiple SVIs in the egress direction 

Applying VACL (VLAN ACL) to multiple VLANs 

Cisco Nexus 9000 Series switch hardware does not support range checks (layer 4 operators) in egress TCAM. 
Because of this, ACL/QoS policies with layer 4 operations-based classification need to be expanded to multiple 
entries in the egress TCAM. Egress TCAM space planning should take this limitation into account. 

Applying the same QoS policy and ACL on multiple interfaces requires applying the qos-policy with the no-
stats option to share the label. 

The following switches support QSFP+ with the QSA (QSFP to SFP/SFP+ Adapter) (40G to 10G QSA): 

N9K-C9396PX 

N9K-C9396TX 

N9K-C93128TX 

N9K-C9372PX, 

N9K-C9372TX 

N9K-C9332PQ 

The Nexus 9300 support for the QSFP+ with QSA adapter has the following limitations

 

Only 10G can be supported using QSA on 40G uplink ports on N9300 switches in NX-OS.   

1G with QSA is not supported. 

All ports in the QSA speed group must operate at the same speed (see the configuration guide). 

The following I/O modules support the breakout cable (40G ports to 4x10G ports): N9K-X9436PQ and N9K-
X9536PQ. 

Limitations for ALE uplink ports are listed at the following URL:
