Limitations and Restrictions Limitations and Restrictions You should review this section before you begin working with the switch. These are known limitations that will not be fixed, and there is not always a workaround. Some features might not work as documented, and some features could be affected by recent changes to the switch hardware or software.
Limitations and Restrictions Address Resolution Protocol • The switch might place a port in an error-disabled state due to an Address Resolution Protocol (ARP) rate limit exception even when the ARP traffic on the port is not exceeding the configured limit. This could happen when the burst interval setting is 1 second, the default. The workaround is to set the burst interval to more than 1 second. We recommend setting the burst interval to 3 seconds even if you are not experiencing this problem.
Limitations and Restrictions • When there is a VLAN with protected ports configured in fallback bridge group, packets might not be forwarded between the protected ports. The workaround is to not configure VLANs with protected ports as part of a fallback bridge group. (CSCsg40322) • When a switch port configuration is set at 10 Mb/s half duplex, sometimes the port does not send in one direction until the port traffic is stopped and then restarted.
Limitations and Restrictions The EtherChannel ports are put in the error-disabled state because the switches in the partitioned stacks send STP BPDUs. The switch or stack at the other end of the EtherChannel receiving the multiple BPDUs with different source MAC addresses detects an EtherChannel misconfiguration. After the partitioned stacks merge, ports in the suspended state should automatically recover.
Limitations and Restrictions • When IEEE 802.1x authentication with VLAN assignment is enabled, a CPUHOG message might appear if the switch is authenticating supplicants in a switch stack. The workaround is not use the VLAN assignment option. (CSCse22791) Multicasting • Multicast packets with a time-to-live (TTL) value of 0 or 1 are flooded in the incoming VLAN when all of these conditions are met: – Multicast routing is enabled in the VLAN.
Limitations and Restrictions Quality of Service (QoS) • When QoS is enabled and the egress port receives pause frames at the line rate, the port cannot send packets. There is no workaround. (CSCeh18677) • Egress shaped round robin (SRR) sharing weights do not work properly with system jumbo MTU frames. There is no workaround.
Limitations and Restrictions The workaround is to reduce the number of OSPF neighbors to 200 or less. (CSCse65252) • When the PBR is enabled and QoS is enabled with DSCP settings, the CPU utilization might be high if traffic is sent to unknown destinations. The workaround is to not send traffic to unknown destinations. (CSCse97660) SPAN and RSPAN • When egress SPAN is running on a 10-Gigabit Ethernet port, only about 12 percent of the egress traffic is monitored. There is no workaround.
Important Notes • If you enter the show tech-support privileged EXEC command after you enter the remote command {all | stack-member-number} privileged EXEC command, the complete output does not appear. The workaround is to use the session stack-member-number privileged EXEC command. (CSCsz38090) VLANs • When the domain is authorized in the guest VLAN on a member switch port without link loss and an Extensible Authentication Protocol over LAN (EAPOL) is sent to an IEEE 802.
Important Notes Cisco IOS Notes • If the switch requests information from the Cisco Secure Access Control Server (ACS) and the message exchange times out because the server does not respond, a message similar to this appears: 00:02:57: %RADIUS-4-RADIUS_DEAD: RADIUS server 172.20.246.206:1645,1646 is not responding. If this message appears, make sure that there is network connectivity between the switch and the ACS.
Important Notes Beginning in privileged EXEC mode, follow these steps to configure the HTTP server interface: Command Purpose Step 1 configure terminal Enter global configuration mode. Step 2 ip http authentication {aaa | enable | local} Configure the HTTP server interface for the type of authentication that you want to use. • aaa—Enable the authentication, authorization, and accounting feature. You must enter the aaa new-model interface configuration command for the aaa keyword to appear.
Open Caveats Open Caveats • CSCtg98453 When you make port security changes on an interface, such as configuring aging time, violations, or aging type, error messages and tracebacks might appear. There is no workaround.
Resolved Caveats When VTp mode is set to transparent and vlan.dat file present in flash is deleted, after reload, access vlan is not configured in the switch even though vlan configuration is present in running config or startup config. The workaround is to set the vtp mode to server or client. • CSCuj81498 The internal port links between 3020 switches and blade servers do not work when you start the switch and the server with a specific power on and off sequence. The workaround is to restart the switch.
Resolved Caveats After rebooting a Cisco Catalyst Blade Switch 3012 (CBS3012), incorrect data is found in the vital product data (VPD) of the switch, which causes the switch to become unmanageable. There is no workaround. • CSCui41032 Switch runs out of memory within few seconds of configuring the command privilege exec level show spanning-tree active/detail. There is no workaround. Caveats Resolved in Cisco IOS Release 15.
Resolved Caveats • CSCub85948 Memory leak is seen in the switch when it sends CDP, LLDP or DHCP traffic and when the link flaps.
Resolved Caveats • CSCth59458 If a redundant power supply (RSP) switchover occurs during a bulk configuration synchronization, some of the line configurations might disappear. The workaround is to reapply the line configurations. • CSCtl12389 The show ip dhcp pool command displays a large number of leased addresses. The workaround is to turn off ip dhcp remember and reload the switch.
Resolved Caveats Heavy traffic load conditions may cause the loop guard protection function to be automatically activated and almost immediately deactivated. These conditions can be caused by entering the shutdown and no shutdown interface configuration commands or by interface link flaps on more than forty ports. These log messages appear: %SPANTREE-2-LOOPGUARD_BLOCK: Loop guard blocking port GigabitEthernet1/0/1 on MST0.
Resolved Caveats Caveats Resolved in Cisco IOS Release 15.0(2)SE • CSCto78529 After upgrading to Cisco IOS Release 12.2(58)SE1, the Fa0 port on the switch does not respond to the ping command. The workaround is to use Cisco IOS Release 12.2(55)SE. • CSCtq38500 When an interface is configured with the mls qos command, traffic is not matched by port-based QoS ACLs that use the range option. The workaround is to is to configure the switch using the single port eq keyword.
Resolved Caveats There is no workaround. • CSCts36715 Users connecting to the network through a device configured for web proxy authentication may experience a web authentication failure. There is no workaround. Use the clear tcp tcb command to release the HTTP Proxy Server process. • CSCtt11621 Using the dot1x default command on a port disables access control on the port and resets the values of the authentication host-mode and authentication timer reauthenticate commands to the default values.
