Enhancements to Display of UDP Connections over
IPv4
In this Software Version, the display of information about UDP connections has
been improved for connections over IPv4, with the following changes to the
output for the command show ip udp:
■ A new Process field displays the process that is using each connection.
■ The Local address field now displays the IP address of the last interface
that was used to transport UDP packets from the device, for the given
process.
Command Changes
The following table summarises the modified command:
Waiting for a Response to an ARP Request
When a router or switch receives a packet and does not have an ARP entry for
the destination address, it broadcasts an ARP Request message over the egress
IP interface. If the router or switch does not receive a reply within a particular
time, it notifies the sending device that the destination is unknown.
This enhancement lets you increase the length of time that the router or switch
waits for a response, which is useful for routers or switches that communicate
with devices that are slow to respond. To configure the waiting time, use the
following new command to specify the wait timeout period in seconds:
set ip arpwaittimeout=1..30
The default is 1 second.
The easiest way to test a changed wait timeout period is to ping an unavailable
device. The timeout determines the delay between pinging an IP address and
receiving the reply that the device is unreachable.
