Installation and Getting Started Guide
• 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).
4. Click Apply to save the changes to the device's running-config file.
5. 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.
To override the global negotiation mode for an individual port:
1. Log on to the device using a valid user name and password for read-write access. The System configuration
panel is displayed.
2. Click on the plus sign next to Configure in the tree view to display the configuration options.
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.
Limiting Broadcast, Multicast, or Unknown-Unicast Rates
HP devices forward all traffic at wire speed. However, some third-party networking devices cannot handle high
forwarding rates for these types of packets. You can limit the number of broadcast, multicast, or unknown-unicast
packets an HP device forwards each second using the following methods.
The limits are individually configurable for broadcasts, multicasts, and unknown-unicasts.
NOTE: By default, IP Multicast (including IGMP) is disabled. You can enable it using the ip multicast passive |
active command. As long as IP Multicast is enabled (regardless of whether it is passive or active), no IP Multicast
packets (not even IGMP packets) are limited. See "Configuring IP Multicast Traffic Reduction (HP 6208M-SX
only)" on page 9-47.
Limiting Broadcasts
To limit the number of broadcast packets an HP device can forward each second, use the following CLI method.
USING THE CLI
To globally limit the number of broadcast packets an HP 9304M or HP 9308M routing switch forwards to 100,000
per second, enter the following command at the global CONFIG level of the CLI:
HP9300(config)# broadcast limit 100000
HP9300(config)# write memory
