ACL Filter Policy Overview
Assignment of filter policies to Interfaces, SAPs and SDPs is allowed up to the maximum number
of filter policies supported per FlexPath (unchanged). If a maximum supported on a given FlexPath
is breached, the configuration change to a filter policy is blocked. Due to a co-existence of
dynamic filter policy entries in the system, an operator-configured filter policy may still fail to be
installed in hardware later on. If that is the case, a trap will be raised for the impacted filter
policies. It is recommended that the operator remove extra filter entries as operational conditions,
such as an IOM reset for example may cause different filter entries to be activated when FlexPath
limits are exceeded.
Note that a filter policy applied to a spoke, or to a SAP/Interface that resides on multiple line cards
(for example, when a LAG or G.8032 rings with links on multiple cards are used), will be
downloaded to all FlexPaths on all cards on which the SAP/interface resides.
Since only the active filter policies are downloaded to a given line card, counters for filter entries
are available only for those filters that are downloaded to one or more line cards.
