• 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).

8. 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 can forward all traffic at wire speed. However, some third-party networking devices cannot handle
high forwarding rates for broadcast, multicast, or unknown-unicast 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. You can configure limits
globally and on individual ports. The valid range is 1 – 4294967295 packets per second. If you specify 0, limiting
is disabled. Limiting is disabled by default.
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.
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 9300 series 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
To limit the number of broadcast packets sent on port 1/3 to 80,000, enter the following commands:
HP9300(config)# int ethernet 1/3
HP9300(config-if-1/3)# broadcast limit 80000
HP9300(config-if-1/3)# write memory
USING THE WEB MANAGEMENT INTERFACE
You cannot perform this procedure using the Web management interface.
Limiting Multicasts
To limit the number of multicast packets an HP device can forward each second, use the following CLI method.
USING THE CLI
To globally limit the number of multicast packets an HP 9300 series Routing Switch forwards to 120,000 per
second, enter the following command at the global CONFIG level of the CLI:
HP9300(config)# multicast limit 120000
HP9300(config)# write memory
To limit the number of multicast packets sent on port 3/6 to 55,000, enter the following commands:
HP9300(config)# int ethernet 3/6
HP9300(config-if-3/6)# multicast limit 55000
HP9300(config-if-3/6)# write memory
