Receive ACLs (rACL)
Cisco 12000 alternation Gigabit Switch Routers (GSR) and 7500 platforms abutment Accept ACL (rACL) to increase
security and thereby assure the router from accidental and potentially abominable traffic. High volumes of data
sent to the GRP can be overwhelming, consistent in an able denial-of-service (DoS) attack. GSRs charge to be
protected adjoin such scenarios, which may aftereffect from DoS attacks directed at the GRP of the router. There
are few techniques accessible to allay DoS, such as rate-limiting cartage destined to the GRP from the line
cards. Unfortunately, this access comes with a accommodation and some limitations. The amount attached for normalpriority
traffic destined to the GRP does not agreement aegis to acute traffic, such as routing
protocol abstracts in the accident of an advance channeled via several band cards.
Receive ACL can be configured application the afterward all-around agreement command and broadcast to anniversary line
card in the router. Standard and continued ACL numbers are accurate for rACL.
