The status monitoring facility provides information about the Switch. This information may be useful for your technical support representative if you have a problem.
Table 10-1 describes the show commands available on the Switch.
Table 10-1: Switch Monitoring Commands
Command Description
show account Displays the account names, access level, number of successful and failed login attempts, and the number of active sessions in the user database. This
show fdb {all | <macaddress> | vlan <name> | <portlist> | permanent}
Displays the forwarding database contents including MAC address, associated VLAN, port, age-of-entry configuration method, and status. Providing one of the options acts as a filter on the display. Providing a VLAN name displays all entries for the VLAN. Use the MAC address to locate a specific entry in the FDB.
show ip config {vlan <name> | all} Displays configuration information for one or more VLANs, including the following:
■ IP address, subnet mask ■ IP forwarding information ■ BOOTP configuration ■ VLAN name, VLANid ■ Global ICMP configuration ■ Global IGMP configuration ■ Global IRDP configuration show iparp {<ip_address> | vlan
<name> | all | permanent}
Displays the current Address Resolution Protocol (ARP) cache for a selected IP address, VLAN, or all entries. With no options, information for all VLANs is displayed.
Information displayed includes IP address, MAC address, aging timer value, VLAN name, VLANid, and port number.
show ipfdb {<ipaddress> | vlan <name> | all}
Displays the contents of the IP forwarding database table. Use for technical support purposes.
show ipmcroute {vlan <name> | all | permanent}
Displays the contents of the IP multicast route table. show iproute vlan {<name> | all |
permanent}
Displays the contents of the IP routing table. show ipstats {vlan [<name> | all]} Displays statistics of packets handled by the CPU,
including the following: ■ inpackets, outpackets ■ ICMP/IGMP statistics ■ IRDP statistics

STATUS MONITORING
show log {<priority>} {<subsystem>} Displays the current snapshot of the log. Options include:
■ priority — Filters the log to display message with the selected priority or higher (more critical). Priorities include critical, warning, and
informational. If not specified, informational priority messages and higher are displayed.
■ subsystem — Filters the log to display messages associated with the selected Switch subsystem. Subsystems include Syst, STP Brdg, SNMP, Telnet, VLAN, and Port. If not specified, all subsystems are displayed.
show log config Displays the log configuration, including the syslog host IP address, the priority level of messages being logged locally, and the priority level of messages being sent to the syslog host.
show management Displays network management configuration and statistics including enable/disable states for Telnet and SNMP, SNMP community strings, authorized SNMP station list, SNMP trap receiver list, and login statistics.
show memory Displays the current system memory information. show port <portlist> collisions Displays collision statistics for each port.
show port <portlist> config Displays state, link status, speed, and autonegotiation setting for each port.
show port <portlist> errors Displays error information for one or more ports. show port <portlist> packet Displays a histogram of packet statistics for one or
more ports.
show port <portlist> stats Displays port information including physical layer configuration and statistics.
show protocol {<protocol>< | all} Displays protocol information including protocol name, protocol fields, and the list of VLANs that use this protocol.
show qosprofile {<qosname> | all} Displays QoS profile information including the QoS profile name, minimum bandwidth, maximum
Table 10-1: Switch Monitoring Commands (continued)
show rip {vlan <name> | all} Displays RIP configuration and statistics for one or more VLANs. Display includes the state for RIP settings, and interface states. Statistics include the following:
■ Packets transmitted ■ Packets received ■ Bad packets received ■ Bad routes received ■ Number of RIP peers ■ Peer information
show rip stat {vlan <name> | all} Displays RIP-specific statistics. Statistics include the following per interface:
■ Packets transmitted ■ Packets received ■ Bad packets received ■ Bad routes received ■ Number of RIP peers ■ Peer information
show session Displays the currently active Telnet and console sessions communicating with the Switch. Provides the user name, IP address of the incoming Telnet session, whether a console session is currently active, and login time. Sessions are numbered. show stpd {<stpd_name> | all} Displays STP information for the one or all STP
domains.
show stpd <stpd_name> port <portlist> Displays port-specific STP information including STP port configuration and state.
