OL-23400-01
Source and destination MAC-based ACLs for filtering non-IP traffic
Support for 3DES and AES with version 3 of the Simple Network Management Protocol (SNMPv3).
This release adds support for the 168-bit Triple Data Encryption Standard (3DES) and the 128-bit,
192-bit, and 256-bit Advanced Encryption Standard (AES) encryption algorithms to SNMPv3.
Cisco modular quality of service (QoS) command-line (MQC) implementation
Three levels of hierarchical output queueing
Classification based on IP precedence, Differentiated Services Code Point (DSCP), and IEEE
802.1p class of service (CoS) packet fields, ACL lookup, and multiprotocol label switching (MPLS)
Experimental bits, or assigning a discard class or QoS label for output classification
Policing
– One-rate policing based on average rate and burst rate for a policer
Two-color policing that allows different actions for packets that conform to or exceed the rate
–
Ingress two-rate, three-color policing for individual or aggregate policers
–
Weighted tail drop (WTD) as the congestion-avoidance mechanism for managing the queue lengths
and providing drop precedences for different traffic classifications
Queuing and Scheduling
Deficit round robin traffic shaping to mix packets from all queues to minimize traffic burst
–
Class-based traffic shaping to specify a maximum permitted average rate for a traffic class
–
Port shaping to specify the maximum permitted average rate for a port
–
– Class-based weighted queuing (CBWFQ) to control bandwidth to a traffic class
– WTD to adjust queue size for a specified traffic class
– Low-latency priority queuing to allow preferential treatment to certain traffic
Per-port, per-VLAN QoS to control traffic carried on a user-specified VLAN for a given interface.
You can use hierarchical policy maps for per-VLAN classification and apply the per-port,
per-VLAN hierarchical policy maps to trunk ports.
IEEE 802.1Q tunneling on EFPs to enable service providers to offer multiple point Layer 2 VPN
services to customers
Layer 2 protocol tunneling on EFPs to enable customers to control protocols, such as BPDU, CDP,
VTP, LLDP, MSTP, PAgP, LACP, and UDLD protocols, to be tunneled across service-provider
networks.
Support for Ethernet over multiprotocol layer switching (EoMPLS) tunneling mechanism for
transporting Ethernet frames over a service-provider MPLS network
Support for Layer 2 transport over MPLS interworking for Ethernet and VLAN interworking.
Pseudowire redundancy to allow service providers to configure their multiprotocol label switching
(MPLS) networks to detect network failures and to reroute Layer 2 services to another endpoint.
