Release Notes for the Cisco ME 3400 Ethernet Access Switch, Cisco IOS Release 12.2(44)SE
OL-14632-01
Minimum Cisco IOS Release for Major Features
New Hardware Features
For a list of all supported hardware, see the “Hardware Supported” section on page 2.
New Software Features
These are the new software features for Cisco IOS Release 12.2(44)SE:
• DHCP-based autoconfiguration and image update to download a specified configuration and image
to a large number of switches
• Configurable small-frame arrival threshold to prevent storm control when small frames (64 bytes or
less) arrive on an interface at a specified rate (the threshold)
• Source Specific Multicast (SSM) mapping for multicast applications to provide a mapping of source
to allowing IGMPv2 clients to utilize SSM, allowing listeners to connect to multicast sources
dynamically and reducing dependencies on the application
• Support for the *, ip-address, interface interface-id, and vlan vlan-id keywords with the clear ip
dhcp snooping command
• Flex Link Multicast Fast Convergence, which reduces the multicast traffic convergence time after a
Flex Link failure
• IEEE 802.1x readiness check to determine the readiness of connected end hosts before configuring
IEEE 802.1x on the switch
• Configurable control-plane queue assignment to assign control plane traffic for CPU-generated traffic to
a specific egress queue
• Configurable control plane security that provides service providers with the flexibility to drop
customers control-plane traffic on a per-port, per-protocol basis. Allows configuring of enhanced
network interfaces (ENIs), customer-facing ports that support protocol control packets
