HP Cisco Catalyst Blade Switch 3020 Release Notes for the Cisco Catalyst Blade - Page 15

Open Caveats • CSCse33321 The Ethernet interface fa0 loses and regains its link because of a DHCP IP address timeout. This situation exists when the HP Onboard Administrator acts as the DHCP server and provides the IP address to the fa0 interface. This occurs when using the clear arp-cache privileged EXEC command to explicitly clear the ARP table. The workaround is to add a static ARP table entry for the DHCP server (in this case, the Onboard Administrator) to the switch and to increase the lease time of the DHCP IP address on the server. • CSCsf98370 Fiber optic small form-factor pluggable (SFP) modules do not establish a link when you configure the Ethernet interfaces with the speed nonegotiate interface configuration command. The workaround is to remove the speed nonegotiate setting for the Ethernet interface that has the fiber SFP installed. This configuration has to be done on the link partner device as well. • CSCsg21537 When MAC addresses are learned on an Etherchannel port, the addresses are incorrectly deleted from the MAC address table even when the MAC address table aging timeout value is configured to be longer than the ARP timeout value. This causes intermittent unicast packet flooding in the network. The MAC address is automatically relearned after the ARP refresh. The workaround is to enter the ping ip address privileged EXEC command from the switch to the next hop router to avoid the intermittent flooding. • CSCsg48163 When the flowcontrol setting for received pause frames is enabled, the switch shows the operational state as off. There is no workaround. • CSCsi63999 Changing the spanning tree mode from rapid STP to MSTP can cause tracebacks when the virtual port error-disable feature is enabled when the STP mode is changed. There is no workaround. • CSCsi75246 An address learned as a supplicant that is aged out by port security aging is never relearned by port security under any of these conditions: - IEEE 802.1x authentication, port security, and port security aging are enabled on a port. - An address is cleared by port security. - You enter the clear port security privileged EXEC command. The workaround is to use the dot1x timeout interface configuration command instead of the port security aging timer as the reauthentication timer for IEEE 802.
