Specifying Addresses and Identifiers in Commands

This section describes addresses and other identifiers that you can reference in CLICommand-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions. commands.

Address or Identifier

Description

IP address

For any command that requires entry of an IP address to specify a network entity, use IPv4 network address format in the conventional dotted decimal notation (for example, 10.4.1.258).

NetmaskNetmask is a 32-bit mask used for segregating IP address into subnets. Netmask defines the class and range of IP addresses. address

For subnetSubnet is the logical division of an IP network. addresses, specify a netmaskNetmask is a 32-bit mask used for segregating IP address into subnets. Netmask defines the class and range of IP addresses. in dotted decimal notation (for example, 255.255.255.0).

MACMedia Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network.

For any command that requires entry of a device’s hardware address, use the hexadecimal format (for example, 00:05:4e:50:14:aa).

SSIDService Set Identifier. SSID is a name given to a WLAN and is used by the client to access a WLAN network.

A unique character string (sometimes referred to as a network name), consisting of no more than 32 characters. The SSIDService Set Identifier. SSID is a name given to a WLAN and is used by the client to access a WLAN network. is case-sensitive (for example, WLANWireless Local Area Network. WLAN is a 802.11 standards-based LAN that the users access through a wireless connection.-01).

BSSIDBasic Service Set Identifier. The BSSID identifies a particular BSS within an area. In infrastructure BSS networks, the BSSID is the MAC address of the AP. In independent BSS or ad hoc networks, the BSSID is generated randomly.

Networks using 802.11a operate at radio frequencies in the 5 GHz band. The specification uses a modulation scheme known as orthogonal frequency-division multiplexing (OFDM) that is especially well suited to use in office settings. The maximum data transfer rate is 54 Mbps. and 802.11g802.11g offers transmission over relatively short distances at up to 54 Mbps, compared with the 11 Mbps theoretical maximum of 802.11b standard. 802.11g employs Orthogonal Frequency Division Multiplexing (OFDM), the modulation scheme used in 802.11a, to obtain higher data speed. Computers or terminals set up for 802.11g can fall back to speed of 11 Mbps, so that 802.11b and 802.11g devices can be compatible within a single network.—used from the AP. Use the same format as for a MACMedia Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network. address.

Typically the unique logical name of a wireless network. If the ESSIDExtended Service Set Identifier. ESSID refers to the ID used for identifying an extended service set. includes spaces, you must enclose the name in quotation marks.

Any command that references a Fast EthernetEthernet is a network protocol for data transmission over LAN. or Gigabit EthernetEthernet is a network protocol for data transmission over LAN. interface requires that you specify the corresponding port on the managed device in the format <slot>/<module>/<port>:

Use the show port status command to obtain the interface information currently available from a managed device.
