3750 Metro Series Switches, ME 3400
and 2400 Series Ethernet Access Switches, and Catalyst Express 500 Series Switches. This new release furthers
Cisco leadership in providing secure, reliable, and feature-rich Metro Ethernet switching solutions as well as
localization on the Cisco Catalyst Express 500 Series.
This product bulletin contains content and delivery information for Cisco IOS Software Release 12.2(25)SEG.
The following new features are available with Cisco IOS Software Release 12.2(25)SEG:
●
Cisco Catalyst Express 500 localization: The device manager for the Cisco Catalyst Express 500 now comes in six additional
languages: Japanese, Chinese (simplified), French, Italian, German, and Spanish. Individual languages may be selected when
accessing the device manager during express setup.
●
Ingress per-port per-virtual LAN (VLAN) policing: Provides ingress quality-of-service (QoS) policing on a per-VLAN basis on a
trunk port.
●
802.1ag connectivity fault management Ethernet Operations, Administration and Maintenance (OAM). 802.1ag is the IEEE
standard for Layer 2 ping, Layer 2 traceroute, and end-to-end connectivity check of Ethernet “circuit.”
●
Ethernet Local Management Interface (ELMI): ELMI is a protocol between the service provider network and the customer
equipment. It lets the customer equipment communicate its status and different service characteristics to the service provider
network to ease troubleshooting and deployments.
●
Configurable per-VLAN MAC learning: Allows disabling MAC address learning on a VLAN to limit the size of the MAC
address table.
●
Open Shortest Path First (OSPF) network types—point-to-point and nonbroadcast: Supports two additional OSPF network types:
point-to-point and nonbroadcast.
●
Layer 2 Protocol Tunneling (L2PT) on trunk port: Allows service providers to tunnel their enterprise customers’ Layer 2 protocols
on trunk ports.
●
Intermediate System-to-Intermediate System (IS-IS): IS-IS is an Open Systems Interconnection (OSI) link-state hierarchical routing
protocol based on DECnet Phase V routing, whereby intermediate systems (routers) exchange routing information based on a single
metric to determine network topology.
●
Network Node Interface (NNI) on all ports on MetroIPAccess image: Currently, Cisco ME3400 Series Ethernet Access Switches
have a limit of four NNIs. This provides a configurable option to allow the restriction to be removed on the MetroIPAccess image.
●
IEEE 802.1S compliance: This enhancement brings the Cisco Multiservice Transport Protocol (MSTP) implementation up to the
IEEE 802.1s standard, while retaining backward compatibility with the Cisco prestandard implementation.
●
Non-stop forwarding (NSF) awareness: This feature enhances the Border Gateway Protocol (BGP), IS-IS, OSPF, and Enhanced
Interior Gateway Routing Protocol (EIGRP) routing protocols so that they are “aware” of being connected to a router supporting
Cisco NSF. It speeds convergence when the NSF router goes through a failover sequence.
