ISCLI Command Modes The ISCLI has three major command modes listed in order of increasing privileges, as follows: User EXEC mode This is the initial mode of access. By default, password checking is disabled for this mode, on console. Privileged EXEC mode This mode is accessed from User EXEC mode. This mode can be accessed using the following command: enable Global Configuration mode This mode allows you to make changes to the running configuration. If you save the configuration, the settings survive a reload of the G8264CS. Several sub‐modes can be accessed from the Global Configuration mode. For more details, see Table 2. This mode can be accessed using the following command: configure terminal Each mode provides a specific set of commands. The command set of a higher‐privilege mode is a superset of a lower‐privilege mode—all lower‐privilege mode commands are accessible when using a higher‐privilege mode. The following table lists the ISCLI command modes. Table 2.

Global Commands Some basic commands are recognized throughout the ISCLI command modes. These commands are useful for obtaining online help, navigating through the interface, and for saving configuration changes. For help on a specific command, type the command, followed by help. Table 3. Description of Global Commands Command Action Provides more information about a specific command or lists commands available at the current level. list Lists the commands available at the current level. exit Go up one level in the command mode structure. If already at the top level, exit from the command line interface and log out. copy runningconfig Write configuration changes to non‐volatile flash startupconfig memory. logout Exit from the command line interface and log out. traceroute Use this command to identify the route used for station‐to‐station connectivity across the network. The format is as follows: traceroute [{<hostname>|<IP address>} [<max‐hops (1‐32)> [<msec‐delay (1‐4294967295)>]][dataport|mgtport]] Where: hostname/IP address: Sets the hostname or IP address of the target station. maxhops: Sets the maximum distance to trace. msecdelay: Sets the number of milliseconds ...

Table 3. Description of Global Commands Command Action telnet This command is used to form a Telnet session between the switch and another network device. The format is as follows: telnet [{<hostname>|<IP address>} [<service port (1‐65535)>][dataport|mgtport]] Where: hostname/IP address: Sets the target station. port: Sets the logical Telnet port or service number. By default, the management port is used. To use a specific port, use the following options: data port: dataport management port: mgtport Note: The DNS parameters must be configured if specifying hostnames. show history This command displays the last ten issued commands. show who Displays a list of users who are currently logged in. show line Displays a list of users who are currently logged in, in table format.

User Access Levels To enable better switch management and user accountability, three levels or classes of user access have been implemented on the G8264CS. Levels of access to CLI, Web management functions, and screens increase as needed to perform various switch management tasks. Conceptually, access classes are defined as follows: user Interaction with the switch is completely passive—nothing can be changed on the G8264CS. Users may display information that has no security or privacy implications, such as switch statistics and current operational state information. oper Operators can make temporary changes on the G8264CS. These changes are lost when the switch is rebooted. Operators have access to the switch management features used for daily switch operations. Because any changes an operator makes are undone by a reboot of the switch, operators cannot severely impact switch operation. admin Administrators are the only ones that may make permanent changes to the switch configuration—changes that are persistent across a reboot of the switch. Administrators can access switch functions to configure and troubleshoot problems on the G8264CS. Because administrators can also make temporary (operator‐level) changes as well, they must be aware of the interactions between temporary and permanent changes. Access to switch functions is controlled through the use of unique surnames and passwords. Once you are connected to the switch via local Telnet, remote Telnet, or SSH, you are prompted to enter a password. The default user names/password for each access level are listed in the following table. Note: It is recommended that you change default switch passwords after initial configuration and as regularly as required under your network security policies. Table 4. User Access Levels User Account Description and Tasks Performed Password User The User has no direct responsibility for switch ...

FDB Information The forwarding database (FDB) contains information that maps the media access control (MAC) address of each known device to the switch port where the device address was learned. The FDB also shows which other ports have seen frames destined for a particular MAC address. Note: The master forwarding database supports up to 128K MAC address entries on the MP per switch. Table 21. FDB Information Options Command Syntax and Usage show macaddresstable Displays all entries in the Forwarding Database. Command mode: All show macaddresstable all Displays all unicast and multicast entries in the Forwarding Database. Command mode: All show macaddresstable address <MAC address> Displays a single database entry by its MAC address. You are prompted to enter the MAC address of the device. Enter the MAC address using the format, xx:xx:xx:xx:xx:xx. For example, 08:00:20:12:34:56. You can also enter the MAC address using the format, xxxxxxxxxxxx. For example, 080020123456.

When in the aggregation (TRK) state, the port field represents the Link Aggregation Group (LAG) number. If the state for the port is listed as unknown (UNK), the MAC address has not yet been learned by the switch, but has only been seen as a destination address. When an address is in the unknown state, no outbound port is indicated, although ports which reference the address as a destination are listed under “Reference ports.” Clearing Entries from the Forwarding Database To clear the entire FDB, refer to “Forwarding Database Maintenance” on page 647.

A monitor port’s Failover status is Operational only if all the following conditions hold true: Port link is up. If Spanning‐Tree is enabled, the port is in the Forwarding state. If the port is a member of an LACP Link Aggregation Group (LAG), the port is aggregated. If any of these conditions are not true, the monitor port is considered to be failed. A control port is considered to be operational if the monitor trigger state is Up. Even if a port’s link status is Down, Spanning‐Tree status is Blocking, and the LACP status is Not Aggregated, from a teaming perspective the port status is Operational, since the trigger is Up. A control port’s status is displayed as Failed only if the monitor trigger state is Down. G8264CS Command Reference for ENOS 8.4...
