You can specify a list of up to 448 MAC SAs thatare authorized to access the switch. You can also specify the ports thateach MAC SA is allowed to access. The options for allowed MAC SA portaccess include: NONE, ALL, and single or multiple ports that are specifiedin a list, for example, one to four, six, nine, and so on. You must also includethe MAC SA of any router connected to any secure ports.After the switch software detects an SA security violation, the response canbe to send a trap, turn on Destination Address (DA) filtering for all SAs,disable the specific port, or any combination of these three options.You can also configure the Ethernet Routing Switch 2500 Series to dropall packets that have a specified MAC Destination Address (DA). You cancreate a list of up to 10 MAC DAs that you want to filter. The packet withthe specified MAC DA is dropped regardless of the ingress port, SourceAddress (SA) intrusion, or VLAN membership.Nortel Ethernet Routing Switch 2500 SeriesSecurity — Configuration and ManagementNN47215-505 (323165-B) 02.01 Standard4.1 19 November 2007Copyright © 2007, Nortel Networks.
