Cisco Cisco IOS XR Software Release 4.3
ACL-Chaining
ACL-Chaining also known as Multi-ACL enables customers to apply two IPv4 or IPv6 (common and interface) ACLs on an interface
for packet filtering at the router. One ACL is common across multiple interfaces on the line card. This provides Ternary Content
Addressable Memory(TCAM)/HW scalability. This feature is supported on A9K-SIP-700 Line Card and ASR 9000 Enhanced Ethernet
Line Card only.

ACL Scale Enhancements
The Access Control List (ACL) Scale enhancements feature enables you to define ACL rules as a set of several rules (super-set of
ACEs (Access Control Entry)). This is achieved with object-groups of prefixes and ports, which are referred by ACE in the same
way as single source address or destination address prefix and ports are referred.

ATMoMPLS Cell Relay Virtual Path Mode
ATM VP Mode cell relay feature enables you to transmit and receive traffic based on the virtual path (VP) configured on the provider
edge (PE) router over an MPLS network. The cell relay feature is supported for virtual path, and on pseudowire of type 0x000A ATM
n-to-one VPC cell transport where n equals 1.

Bandwidth Reservation Percentage
The Bandwidth Reservation Percentage allows the RSVP interface bandwidth to be specified as percentages of the link's physical
bandwidth.

IP-Less MPLS-TP Ping and MPLS-TP Traceroute
According to RFC-6426, IP-Less MPLS-TP ping and MPLS-TP traceroute with the ACH header, if a node receives an MPLS-TP
ping or traceroute request packet over ACH, without IP or UDP headers, the node drops the echo request packet and does not send
a response when:
ping or traceroute request packet over ACH, without IP or UDP headers, the node drops the echo request packet and does not send
a response when:
• the reply mode is 4
• the node does not have a return MPLS LSP path to the echo request source.
