Arp Age Timer Increase - HP ProCurve J8766A Release Note

Enhancements
Release L.11.08 Enhancements
Port Configuration:
The default port configuration is Auto, which enables a port to sense speed and negotiate duplex with
an Auto-Enabled port on another device. ProCurve recommends that you use the Auto setting for all
ports you plan to use for trunking. Otherwise, you must manually ensure that the mode setting for
each port in a trunk is compatible with the other ports in the trunk.
Figure 6. Recommended Port Mode Setting for LACP
Each of the following operate on a per-port basis, regardless of trunk membership:
■ Enable/Disable
Flow control (Flow Ctrl)
■
Trunk Configuration:
All ports in the same trunk group must be the same trunk type (LACP or Trunk). All LACP ports in
the same trunk group must be either all static LACP or all dynamic LACP.
A trunk appears as a single port labeled Dyn1 (for an LACP dynamic trunk) or Trk1 (for a static trunk
of type: LACP, Trunk) on various menu and CLI screens.
For spanning-tree or VLAN operation, configuration for all ports in a trunk is done at the trunk level.
You cannot separately configure individual ports within a trunk for spanning-tree or VLAN operation.
Traffic Distribution:
All of the switch trunk protocols use the SA/DA (Source Address/Destination Address) method of
distributing traffic across the trunked links.

ARP Age Timer Increase

The ARP age is the amount of time the switch keeps a MAC address learned through ARP in the ARP
cache. The switch resets the timer to zero each time the ARP entry is refreshed and removes the entry
if the timer reaches the ARP age.
