PRODUCT BULLETIN NO. 2551

OVERVIEW

Cisco Systems ® announces Cisco IOS ® Software updates for the Cisco ® Catalyst ® 3550, 2955, 2950, 2950-LRE and 2940 series Intelligent Ethernet switches. This new release furthers Cisco leadership in providing secure, reliable, and easily managed LAN switching solutions.
This product bulletin describes the content and delivery information about Cisco IOS Software Release 12.1(22)EA1. For more information about the Cisco IOS Software release process, see Product Bulletin 537.
Catalyst 2940 switch now extends it's support from 4 VLANs in the past to 12 VLANs with this IOS release. This also increases the number of supported STP instances to 12. VLANs are identified with a number from 1 to 4094. VLAN IDs 1002 through 1005 are reserved for Token Ring and FDDI VLANs. VTP only learns normal-range VLANs, with VLAN IDs 1 to 1005; VLAN IDs greater than 1005 are extended-range VLANs and are not stored in the VLAN database. The switch must be in VTP transparent mode when you create VLAN IDs from 1006 to 4094.
With the introduction of 802.1x with Dynamic VLAN assignment on 2940 switches, users can limit network access for certain users by using VLAN assignment. After successful 802.1x authentication of a port, the RADIUS server sends the VLAN assignment to configure the switch port. The RADIUS server database maintains the username-to-VLAN mappings, which assigns the VLAN based on the username of the client connected to the switch port.
With the introduction of 802.1x with Guest VLAN support on 2940 switches, users can configure a guest VLAN for each 802.1x port on the switch to provide limited services to clients (for example, users can download the 802.1x client). These clients might be upgrading their system for 802.1x authentication, and some hosts, such as Windows 98 systems, might not be 802.1x-capable. With the current implementation of this feature, users that do not support the 802.1x supplicant code on their desktop will fail 802.1x authentication and be placed in the guest VLAN.
The Speed Autonegotiate enhancement allows users to enter specific values associated with the capability to Autonegotiate speed and duplex settings of switch ports. As an example, the network manager can configure 10/100/1000 Mbps capable ports to only advertise 10/100 Mbps speeds. This might be used in situations where the core of the network has not yet been scaled to support users at 1000 Mbps. Table 1 below shows the speed and duplex settings that will be supported.

10/100/100 Ethernet Ports

Fiber SFP, GBIC, & XENPAK Uplink Interfaces

Duplex Settings

speed <10 | 100 | auto [10 | 100]>

The user will be able to configure the following different combinations:

speed 10

speed 100

speed auto

speed auto 10

speed auto 100

speed auto 10 100

speed <10 | 100 | 1000 | auto [10 | 100 | 1000]>


The user will be able to configure the following different combinations:
speed 10

speed 100

speed 1000

speed auto

speed auto 10

speed auto 100

speed auto 1000

speed auto 10 100

speed auto 10 1000

speed auto 100 1000

speed auto 10 100 1000

Only one speed is supported on most types of interfaces; Please refer to the Release Notes for more information.

The duplex command will not change.

(Note - half-duplex is not supported on 1000 Mbps and 10000 Mbps interfaces)

The configured status for these speed and duplex commands will be displayed through a new command-show interface transceiver properties.
The storm control feature as implemented on the Cat 3550 allows a port to be blocked if a particular traffic type (multicast, unicast, or broadcast) exceeds a given threshold. The threshold is specified as a percentage of the total bandwidth of the port (%BW). However, customers have requested the option to specify the threshold in packets per second (PPS). In order to meet customer requirements for this feature, Storm control packet per second support has been added with this IOS release on the 3550 switching platform. In addition, the "show storm-control" command output will display port statistics in the same units (PPS or %BW) configured by the user.
