ERROR: 'switchport access vlan' is not supported on L3 interface

[jjevans]

I am trying to add ports to vlan 1000

Vlan 1000

Name vlan

interface Vlan1000

  no shutdown

  no ip redirects

  ip address 10.20.55.1/26

  no ipv6 redirects

  ip router eigrp 100

  ip passive-interface eigrp 100

interface Ethernet1/1-48

switchport mode access

  switchport access vlan 1000

  spanning-tree port type edge

Try to add vlan 1000 to port 1-48 but I get ERROR: eth1/1: 'switchport access vlan' is not supported on L3 interface

I do a show run and none of the ports are assigned to vlan 1000??? Not 1/1 -1/48 What am I doing wrong? TIA

switch# show run 

interface Ethernet1/1

interface Ethernet1/2

interface Ethernet1/3

NXOS image file is: bootflash:///nxos.9.3.2.bin

Looks like interfaces are L3 by default so to change just type "switchport" in interface configuration mode then run your command again.

incorrect you have it backwards

Have what backwards, do you mean they are L2 by default ? 

If so then I guess eth1/1 must have been changed at some point.
