Installation and Getting Started Guide
3. Select the Port link to display the Port table.
4. Click on the Modify button next to the row of information for the port you want to reconfigure.
5. Select one of the following values from the Gig Port Default field's pulldown menu:
• Default – The port uses the negotiation mode that was set at the global level.
• Neg-off – The port does not try to perform a handshake. Instead, the port uses configuration information
manually configured by an administrator.
• Auto-Gig – The port tries to perform a handshake with the other port to exchange capability information.
• Neg-Full-Auto – The port first tries to perform a handshake with the other port to exchange capability
information. If the other port does not respond to the handshake attempt, the port uses the manually
configured configuration information (or the defaults if an administrator has not set the information).
6. Click Apply to save the changes to the device's running-config file.
7. Select the Save link at the bottom of the dialog. Select Yes when prompted to save the configuration change
to the startup-config file on the device's flash memory.
NOTE: You also can access the dialog for saving configuration changes by clicking on Command in the tree
view, then clicking on Save to Flash.
Modifying Port Priority (QoS)
You can give preference to the inbound traffic on specific ports by changing the Quality of Service (QoS) level on
those ports. For information and procedures, see the "Configuring Quality of Service" chapter in the Advanced
Configuration and Management Guide .
Configuring Basic Layer 2 Parameters
The procedures in this section describe how to configure the following Layer 2 parameters.
• Spanning Tree Protocol (STP) – see "Enabling or Disabling the Spanning Tree Protocol (STP)" on page 4-24
NOTE: The procedures in this chapter describe how to configure basic STP parameters. For more
information about STP, see "Configuring Spanning Tree Protocol (STP)" on page 6-1.
• Layer 2 switching of unsupported router protocols – see "Enabling or Disabling Layer 2 Switching" on page 4-
27
• Aging time for learned MAC address entries – see "Changing the MAC Age Time" on page 4-28
• Static, non-aging MAC address entries – see "Configuring Static MAC Entries" on page 4-29
• Port-based VLANs – see "Enabling Port-Based VLANs" on page 4-31
• MAC address filters – see "Defining MAC Address Filters" on page 4-32
• Broadcast and Multicast Filters – see "Defining Broadcast and Multicast Filters" on page 4-37
• Port locks – see "Locking a Port To Restrict Addresses" on page 4-39
Enabling or Disabling the Spanning Tree Protocol (STP)
The STP (IEEE 802.1d bridge protocol) is supported on all HP Routing Switches. STP detects and eliminates
logical loops in the network. STP also ensures that the least cost path is taken when multiple paths exist between
ports or VLANs. If the selected path fails, STP searches for and then establishes an alternate path to prevent or
limit retransmission of data.
STP must be enabled at the system level to allow assignment of this capability on the VLAN level. STP is disabled
by default.
