CLI Conventions 29
The CLI has specific notation requirements for MAC addresses, IP
addresses, and masks, and allows you to group usernames, MAC
addresses, virtual LAN (VLAN) names, and ports in a single command.
3Com recommends that you do not use the same name with different
capitalizations for VLANs or access control lists (ACLs). For example, do
not configure two separate VLANs with the names red and RED.
The CLI does not support the use of special characters including the
following in any named elements such as SSIDs and VLANs: ampersand
(&), angle brackets (< >), number sign (#), question mark (?), or quotation
In addition, the CLI does not support the use of international characters
such as the accented É in DÉCOR.
MAC Address Notation
MSS displays MAC addresses in hexadecimal numbers with a colon (:)
delimiter between bytes—for example, 00:01:02:1a:00:01. You can enter
MAC addresses with either hyphen (-) or colon (:) delimiters, but colons
You can exclude leading zeros when typing a MAC address. MSS
displays of MAC addresses include all leading zeros.
In some specified commands, you can use the single-asterisk (*)
wildcard character to represent an entire MAC address or from 1 byte
to 5 bytes of the address. (For more information, see “MAC Address
Globs” on page 31.)
IP Address and Mask Notation
MSS displays IP addresses in dotted decimal notation—for example,
192.168.1.111. MSS makes use of both subnet masks and wildcard
Subnet Masks Unless otherwise noted, use classless interdomain
routing (CIDR) format to express subnet masks—for example,
192.168.1.112/24. You indicate the subnet mask with a forward slash (/)
and specify the number of bits in the mask.
