The following example shows a typical output of this command, showing that Auto-NAS is enabled
on two IP address (one using VLAN, and one using VRF), that it has a CoS of 2 and DSCP of 0
(defaults) and a Traffic class of 5.
switch# show system internal nas
Auto-NAS Enabled
Cos 2
Dscp 0

NAS server-ip 10.192.100.101/32 vrf broceliande
Specifying NAS server IP addresses for Auto QoS
To enable Auto QoS for NAS, you must identify the IPv4 network addresses used by the NAS devices
and tell the platform to tag all packets with this network address as NAS traffic so that they have the
correct priority.
The nas server-ip command can accept a single IPv4 address (10.192.100.100/32), or an entire sub-
net (10.192.100.0/24 vlan 100) as input. You can specify either a Virtual Routing and Forwarding
(VRF) ID, or a VLAN ID. If no ID identifier is specified, the default VRF is assumed. When a subnet is
specified, all the servers in the sub-net will have Auto QoS enabled for NAS. Subnet masks are not
supported (for example: 10.192.100.0 255.255.255.0 is not a supported address).
NOTE
Only IPv4 addressing is supported for Auto QoS for NAS.
To add a NAS address to the NAS server IP list:
1. In configuration mode, enter nas server-ip followed by the IP address with mask and then one of
the following:
• vlan vlan_ID
• vrf vrf_Name
2. Press Enter after you add each address entry.
The following example adds two addresses, one using a VLAN mask, and the
other a VRF mask.
switch(config)# nas server-ip 10.192.100.100/32 vlan 100
switch(config)# nas server-ip 10.192.100.101/32 vrf broceliande
Removing NAS server IP addresses for Auto QoS
Removing NAS server IP addresses sets the Auto QoS values for those addresses back to their
defaults.
The no nas server-ip command can accept a single IPv4 address (10.192.100.100/32), or an entire
sub-net (10.192.100.0/24 vlan 100) as input. When a subnet is specified, all the servers in the sub-net
will have Auto QoS for NAS removed. Subnet masks are not supported (for example: 10.192.100.0
255.255.255.0 is not a supported address).
To remove an address from the NAS server IP list:
1. In config mode, enter no nas server-ip followed by the IPv4 address including the mask and then
one of the following:
