Release Notes for Cisco Catalyst Blade Switch 3120 for HP, Cisco IOS Release 12.2(52)SE

OL-19714-01

New Features

New Software Features

• Full QoS support for IPv6 traffic.

• Smart Install to allow a single point of management (director) in a network. You can use Smart

Install to provide zero touch image and configuration upgrade of newly deployed switches and

image and configuration downloads for any client switches.

• Cisco Medianet to enable intelligent services in the network infrastructure for a wide variety of

video applications. One of the services of Medianet is auto provisioning for Cisco Digital Media

Players and Cisco IP Video Surveillance cameras through Auto Smartports.

• Support for IP source guard on static hosts.

• RADIUS Change of Authorization (CoA) to change the attributes of a certain session after it is

authenticated. When there is a change in policy for a user or user group in AAA, administrators can

send the RADIUS CoA packets from the AAA server, such as Cisco Secure ACS to reinitialize

authentication, and apply to the new policies.

• IEEE 802.1x User Distribution to allow deployments with multiple VLANs (for a group of users) to

improve scalability of the network by load balancing users across different VLANs. Authorized

users are assigned to the least populated VLAN in the group, assigned by RADIUS server.

• Support for critical VLAN with multiple-host authentication so that when a port is configured for

multi-auth, and an AAA server becomes unreachable, the port is placed in a critical VLAN in order

to still permit access to critical resources.

• Customizable web authentication enhancement to allow the creation of user-defined login, success,

failure and expire web pages for local web authentication.

• Support for Network Edge Access Topology (NEAT) to change the port host mode and to apply a

standard port configuration on the authenticator switch port.

• VLAN-ID based MAC authentication to use the combined VLAN and MAC address information for

user authentication to prevent network access from unauthorized VLANs.

• MAC move to allow hosts (including the hosts connected behind an IP phone) to move across ports

within the same switch without any restrictions to enable mobility. With MAC move, the switch

treats the reappearance of the same MAC address on another port in the same way as a completely

new MAC address.

• Support for including a hostname in the option 12 field of DHCPDISCOVER packets. This provides

identical configuration files to be sent by using the DHCP protocol.

• DHCP snooping enhancement to support the selection of a fixed string-based format for the

circuit-id sub-option of the Option 82 DHCP field.

• Support for VTP version 3 that includes support for configuring extended range VLANs (VLANs

1006 to 4094) in any VTP mode, enhanced authentication (hidden or secret passwords), propagation

of other databases in addition to VTP, VTP primary and secondary servers, and the option to turn

VTP on or off by port.

• Support for the LLPD-MED MIB and the CISCO-ADMISSION-POLICY-MIB.

• Support for up to 32 10 Gigabit Ethernet DWDM X2 optical modules.
