3.1.3.8 ARP
Address Resolution Protocol (ARP) is used to map an IP address to a physical MAC
address on the local area network. The ARP table maintains the relationship between the
IP address and the MAC address.
The aging time is the time in minutes for dynamic entries to remain in the ARP table
before they are removed. When the aging time is reached the switch flushes the entry
from the memory. The MAC address can be either learned by the switch – dynamic or
entered manually.
To configure the ARP aging time enter a figure and select . Then configure the
ARP address including IP, MAC addresses and select to finish. To delete an ARP
address select the item number from the ARP address list and select .
3.1.3.9 RSTP
In this menu both RSTP and STP can be set up. RSTP (Rapid Spanning Tree Protocol) is a
layer 2 management protocol developed from STP (Spanning Tree Protocol) it is
compatible with STP and has all the functionality of STP but is quicker. RSTP defines the
Root Bridge, Root Port, Designated Port, Path Cost and ensures that there are no active
network loops. By creating a tree topology it also optimizes the link backup and path
selection.
Select RSTP or STP to configure this menu. Set the following:
• Spanning Tree Priority - range: 0-65535, default: 32768, step size: 4096
• Hello Time: range - 1-10, default: 2
• Max Age Time - range: 6-40, default: 20
• Forward Delay Time - range: 4-30, default: 15
• Message-age increment to either default or compulsion
Select > t o finish.
Additionally, the protocol status, priority and path cost of each port can be configured.
