DHCP Server Enhancement

You can now configure DHCP vendor-specific options (Option 43) and apply configuration to clients that match a specific vendor class (Option 60).

For more information, see the following sections:

• DHCP Vendor Options

• DHCP Server Configuration (using CLI)

• DHCP Server Configuration using EDM

General Enhancements

This release introduces the following enhancements:

• Additional resource information—The show fulltech command includes information for the show ip arp spbm-tunnel-as-mac [vrf WORD<1-16>] [vrfids WORD<0-512>] command.

• Auto-sense for Fabric Attach (FA) enhancement—You can now configure the management I-SID and C-VID values for FA proxy management and FA proxy ring management independently. In the previous release, the configured management I-SID and C-VID values were used for both FA proxy management and FA proxy ring management.

  For more information, see Configure a Management I-SID for Auto-sense Fabric Attach Proxy Ring Switches.

• EAP enhancement—You can use the clear eapol eap command to clear EAP client sessions on the switch.

  For more information, see the following sections:

  • Clear an EAP Client Session (CLI)

  • View Multihost Status Information (EDM)

• MACsec enhancement—The connectivity association key name increases from 16 to 32 characters for MACsec capable platforms.

  For more information, see the following sections:

  • Configure a Connectivity Association (CLI)

  • Configure Connectivity Associations (EDM)

• Reset the switch—The show software command now displays the number of seconds remaining until the switch resets in addition to the number of days, hours, and minutes.

  For more information, see Reset the Platform.

• SSH enhancement—You can now use either the IS-IS host name or IS-IS system ID with the SSH client on a switch to establish a connection to another switch in the SPBM cloud. The Destination Device Identifier uses the format: "fe80::xxxx:xxxx:xxxx%linuxsshtobmac". The last 48 bits of the link-local address represent the IS-IS system ID, and "linuxsshtobmac" is the native Linux stack interface name used by this enhancement.

  

  Note

  You cannot establish an SSH connection to the boundary node from an IS-IS remote area.

  For more information, see Connect to a Remote Host using the SSH Client.

• Upgrade enhancement—If you attempt to upgrade the software on a switch with inadequate space, the switch can remove log files, if that creates sufficient space to proceed with the upgrade.

  For more information, see Upgrade the Software.

Multicast Lite RADIUS VSA Enhancement

Prior to this release, the Extreme-Dynamic-Client-Assignments Vendor Specific Attribute (VSA) failed if the VLAN and I-SID were statically configured. With this enhancement, configuration is applied even if the VLAN and I-SID are statically configured.

For more information, see the following sections:

• Extreme-Dynamic-Client-Assignments

• Operational Considerations

Power Reporting Enhancement

show sys-info power and show sys power power-supply commands now include current, voltage, and power input and output details for the power supply unit installed in your switch.

For more information, see the following sections:

• Display Power Status (CLI)

• View Power Supply Parameters (EDM)

RADIUS Configuration using Fully Qualified Domain Name (FQDN)

In previous releases, you could only specify an IPv4 or IPv6 address when you configured a RADIUS server host or an IPv4 address for a RADIUS dynamic client. Now, you can use an FQDN, such as host.example.com, instead of an IP address.

For more information, see RADIUS Fundamentals.
