Page 58: Accessing The Cli
Using the Command Line Interface (CLI) Overview Overview The CLI is a text-based command interface for configuring and monitoring the switch. The CLI gives you access to the switch’s full set of commands while providing the same password protection that is used in the web browser interface and the menu interface.
Page 59: Privilege Levels At Logon
Using the Command Line Interface (CLI) Using the CLI When you use the CLI to make a configuration change, the switch writes the change to the Running-Config file in volatile memory. This allows you to test your configuration changes before making them permanent. To make changes permanent, you must use the write memory command to save them to the Startup Config file in non-volatile memory.
Page 60: Privilege Level Operation
Using the Command Line Interface (CLI) Using the CLI C a u t i o n ProCurve strongly recommends that you configure a Manager password. If a Manager password is not configured, then the Manager level is not password- protected, and anyone having in-band or out-of-band access to the switch may be able to reach the Manager level and compromise switch and network security.
Page 61: Manager Privileges
Using the Command Line Interface (CLI) Using the CLI Manager Privileges Manager privileges give you three additional levels of access: Manager, Global Configuration, and Context Configuration. (See figure 4-2.) A “#” character delimits any Manager prompt. For example: ProCurve#_ Example of the Manager prompt. ■...

Port Trunking Port Status and Configuration Fault Tolerance: If a link in a port trunk fails, the switch redistributes traffic originally destined for that link to the remaining links in the trunk. The trunk remains operable as long as there is at least one link in operation. If a link is restored, that link is automatically included in the traffic distribution again.

Page 221 Port Trunking Port Status and Configuration Spanning Tree: Spanning Tree operates as a global setting on the switch (one instance of Spanning Tree per switch). However, you can adjust Spanning Tree parameters on a per-port basis. A static trunk of any type appears in the Spanning Tree configuration display, and you can configure Spanning Tree parameters for a static trunk in the same way that you would configure Spanning Tree parameters on a non-trunked port.
Page 222: Menu: Viewing And Configuring A Static Trunk Group
Port Trunking Port Status and Configuration Menu: Viewing and Configuring a Static Trunk Group Important Configure port trunking before you connect the trunked links to another switch, routing switch, or server. Otherwise, a broadcast storm could occur. (If you need to connect the ports before configuring them for trunking, you can temporarily disable the ports until the trunk is configured.

Page 231 Port Trunking Port Status and Configuration N o t e Dynamic LACP trunks operate only in the default VLAN (unless GVRP is enabled and Forbid is used to prevent the trunked ports from joining the default VLAN). Thus, if an LACP dynamic trunk forms using ports that are not in the default VLAN, the trunk will automatically move to the default VLAN unless GVRP operation is configured to prevent this from occurring.

LACP Trunk Types LACP Port Trunk Operation Configuration 802.3ad-compliant Dynamic LACP This option automatically establishes an trunk group, with LACP for the port Type parameter and DynX for the port Group name, where X is an automatically assigned value 1 to 24 depending on how many dynamic and static trunks are currently on the switch.
Page 233: Default Port Operation
Port Trunking Port Status and Configuration Default Port Operation In the default configuration, all ports are configured for passive LACP. How ever, if LACP is not configured, the port will not try to detect a trunk configuration and will operate as a standard, untrunked port. N o t e Passive and active LACP port will pause and listen for LACP packets once a link is established.
Page 234 Port Trunking Port Status and Configuration Table 11-5. LACP Port Status Data Status Name Meaning Port Numb Shows the physical port number for each port configured for LACP operation (C1, C2, C3 . . .). Unlisted port numbers indicate that the missing ports are assigned to a static Trunk group or are not configured for any trunking.
Page 235: Lacp Notes And Restrictions
Port Trunking Port Status and Configuration LACP Notes and Restrictions 802.1X (Port-Based Access Control) Configured on a Port. To main tain security, LACP is not allowed on ports configured for 802.1X authenticator operation. If you configure port security on a port on which LACP (active or passive) is configured, the switch removes the LACP configuration, displays a notice that LACP is disabled on the port(s), and enables 802.1X on that port.
Page 236 Port Trunking Port Status and Configuration Static LACP Trunks. Where a port is configured for LACP (Active or Passive), but does not belong to an existing trunk group, you can add that port to a static trunk. Doing so disables dynamic LACP on that port, which means you must manually configure both ends of the trunk.

Port Trunking Port Status and Configuration Half-Duplex and/or Different Port Speeds Not Allowed in LACP Trunks. The ports on both sides of an LACP trunk must be configured for the same speed and for full-duplex (FDx). The 802.3ad LACP standard speci fies a full-duplex (FDx) requirement for LACP trunking.

Page 291: Lldp And Cdp Data Management
Configuring for Network Management Applications LLDP (Link-Layer Discovery Protocol) LLDP and CDP Data Management This section describes points to note regarding LLDP (Link-Layer Discovery Protocol) and CDP (Cisco Discovery Protocol) data received by the switch from other devices. LLDP operation includes both transmitting LLDP packets to neighbor devices and reading LLDP packets received from neighbor devices.
Page 292 Configuring for Network Management Applications LLDP (Link-Layer Discovery Protocol) N o t e Because ProCurve switches do not generate CDP packets, they are not represented in the CDP data collected by any neighbor devices running CDP.

Troubleshooting Chassis Over-Temperature Detection Chassis Over-Temperature Detection i. If a switch reaches an over-temperature condition, it generates a chassis-module Warning message in the Event Log and in any optionally configured debug destinations (console session and SyslogD servers). If the switch later returns to its acceptable temperature range, it signals this event with a chassis module Information message to the same destinations.
Page 356 Troubleshooting Chassis Over-Temperature Detection If there are no fan failures, ensure that the ambient temperature in the ■ switch’s operating area is not causing the over-temperature condition. If the condition persists, remove power from the switch until you can find the cause and apply an effective remedy.
