ARP -A Performs Badly When ARP Cache Contains Many Addresses (145587)
The information in this article applies to:
- Microsoft Windows NT Workstation 3.51
- Microsoft Windows NT Server 3.51
This article was previously published under Q145587 SYMPTOMS
When you have several hundred IP addresses in your ARP cache, the execution
of the arp -a command can take an hour or more. To get this many addresses
in your cache, you have to increase ArpCacheLife.
CAUSE
ARP is using SNMP to retrieve the contents of the ARP cache. The SNMP agent
is not designed to query large numbers of objects.
STATUS
Microsoft has confirmed this to be a problem in Windows NT Server and
Workstation versions 3.51 and 4.0. We are researching this problem and will
post new information here in the Microsoft Knowledge Base as it becomes
available.
