Error (Invalid input) when entering an IP address
When using the "host" option in the Command syntax, ensure that you are not including a mask in either dotted decimal or CIDR format. Using the "host" option implies a specific host device and therefore does not permit any mask entry.
Correctly and incorrectly specifying a single host
Switch(config)# access-list 6 permit host 10.28.100.100 1 Switch(config)# access-list 6 permit host 10.28.100.100 255.255.255.2552 Invalid input: 255.255.255.255 Switch(config)# access-list 6 permit host 10.28.100.100/32 3 Invalid input: 10.28.100.100/32
