Software Fixes in Releases Y.11.01 - Y.11.16

Release Y.11.13

■ Config (PR_0000039026) — The switch reloads into a configuration that is copied to the

startup configuration, even if the downloaded config is identical to the one the switch has

stored. This fix will remove the need to reload in that case, and return a message at the CLI:

Downloaded file identical to current, no update performed.

■ Authentication (PR_0000011138) — If the Radius server becomes unavailable, the eap-

radius authorized option allows the switch to authenticate devices. If the response time of the

RADIUS subsystem is greater than the server-timeout value on the switch or the device

supplicant then the switch will not be able to authenticate devices, and no warning of this

failure will be displayed. This fix triggers the display of the following CLI message.

The RADIUS connection timeout must be less than the authentication

server timeout for the switch to authenticate automatically when the

RADIUS server is unavailable.

■ 802.1X (PR_0000010850) — If an unauth-vid is configured, and the client limit is reached

on a switch port, a properly credentialed re-authentication following an improperly creden-

tialed authentication attempt (for example, incorrect password) will leave the 802.1X client

in the unauthorized VLAN instead of applying the appropriate authorized VLAN.

Release Y.11.13

The following problems were resolved in build Y.11.13. (Not a public release.)

■ Authentication (PR_0000038263) — Some frames are allowed on the switch port despite

the default aaa parameter controlled-directions both.

■ CLI (PR_0000010378) — Session time (in seconds) remains at zero in response to the CLI

command show port-access authenticator <port> session-counters; it should increment.

■ Crash (PR_0000041599) — When a configuration file is uploaded to the switch via TFTP

or SCP/SFTP, the switch crashes during attempted reload into the configuration if one or

more of the following lines are present in the configuration.

snmp-server response-source <IP address>

snmp-server response-source dst-ip-of-request

snmp-server trap-source <IP address>

The switch will log a crash message similar to the following.

PPC Bus Error exception vector 0x300: Stack-frame=0x0124cc40 HW

Addr=0x025aa1cc IP=0x00538808 Task='mftTask' Task ID=0 x124dcb0

fp:0x012d5c30 sp:0x0124cd00 lr:0

■ Crash (PR_0000043999) — When the switch is configured with SNMPv3, it may reboot

unexpectedly when a network management server communicates with it using SNMPv3. The

crash message will be similar to the following.
