Cisco ASR 5000 Series Product Overview ▄

There are two primary components of an ACL:
Rule: A single ACL consists of one or more ACL rules. As discussed earlier, the rule is a filter configured to
take a specific action on packets matching specific criteria. Up to 128 rules can be configured per ACL.
Each rule specifies the action to take when a packet matches the specifies criteria. This section discusses the
rule actions and criteria supported by the system.
Rule Order: A single ACL can consist of multiple rules. Each packet is compared against each of the ACL rules,
in the order in which they were entered, until a match is found. Once a match is identified, all subsequent rules
are ignored.

ANSI T1.276 Compliance
ANSI T1.276 specifies security measures for Network Elements (NE). In particular it specifies guidelines for password
strength, storage, and maintenance security measures.
ANSI T1.276 specifies several measures for password security.
These measures include:
Password strength guidelines
Password storage guidelines for network elements
Password maintenance, e.g. periodic forced password changes
These measures are applicable to the ASR 5000 and the Web Element Manager since both require password
authentication. A subset of these guidelines where applicable to each platform will be implemented. A known subset of
guidelines, such as certificate authentication, are not applicable to either product. Furthermore, the platforms support a
variety of authentication methods such as RADIUS and SSH which are dependent on external elements. ANSI T1.276
compliance in such cases will be the domain of the external element. ANSI T1.276 guidelines will only be implemented
for locally configured operators.
APN Support
The GGSN's Access Point Name (APN) support offers several benefits:
Extensive parameter configuration flexibility for the APN.
Creation of subscriber tiers for individual subscribers or sets of subscribers within the APN.
Virtual APNs to allow differentiated services within a single APN.
