Cisco® announces Cisco IOS® Software updates for the Cisco Catalyst® 2950, 2940, and 2955 Series Switches.
This product bulletin contains content and delivery information for Cisco IOS Software Release 12.1(22)EA10.
The following new features are available with Cisco IOS Software Release 12.1(22)EA10:
• Dynamic Host Configuration Protocol (DHCP) snooping statistics: Provides visibility into DHCP snooping for proactive management. Displays statistics about processed packets and various conditions that can cause a packet to be dropped (such as packet not allowed on untrusted port and so on). In addition, rate-limited SYSLOG messages can be generated for notification.
• DHCP auto-install with saved configuration: Simplifies deployment by enabling DHCP-based configuration on the switch, though a basic configuration file is present on the switch.
Table 1 lists new features of Cisco IOS Software Release 12.1(22)EA10.

Because of export restrictions on strong cryptography, a separate image is required for cryptographic features (Secure Shell [SSH] Protocol, Simple Network Management Protocol Version 3 [SNMPv3], and Kerberos Protocol). These software images can be downloaded from the corresponding Triple Data Encryption Standard (3DES) area of the links provided in this section.
