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. • CSCtl32991 Unicast EIGRP packets destined for the switch are sent to the host queue instead of to the higher priority routing protocol queue. Note This does not occur when packets are routed through the switch to another destination. There is no workaround. • CSCtl60247 When a switch running Multiple Spanning Tree (MST) is connected to a switch running Rapid Spanning Tree Protocol (RSTP), the MST switch acts as the root bridge and runs per-VLAN spanning tree (PVST) simulation mode on boundary ports connected to the RST switch. If the allowed VLAN on all trunk ports connecting these switches is changed to a VLAN other than VLAN 1 and the root port of the RSTP switch is shut down and then enabled, the boundary ports connected to the root port move immediately to the forward state without going through the PVST+ slow transition. There is no workaround. • CSCtl81217 When a switch is using a DHCP server to assign IP addresses and an interface on the switch has RIP enabled, if the switch reloads, the interface loses some RIP configuration (specifically RIP authentication mode and RIP authentication key-chain). This does not happen when the IP address is statically configured on the interface. The problem occurs only when you configure RIP before an IP address is assigned by the DHCP server. There is no workaround, but you can use an embedded event manager (EEM) script to add the interface configuration commands on the interface: ip rip authentication mode ip rip key-chain • CSCtq01926 When you configure a port to be in a dynamic VLAN by entering the switchport access vlan dynamic interface configuration command on it, the switch might reload when it processes ARP requests on the port. The workaround is to configure static VLANs for these ports. • CSCtx69656 After the switch boots up, a connected device does not receive Gratuitous ARP (GARP) packets from the switch. The workaround is to perform one of the following actions: - clear the ARP cache on the connected device - use the switchport nonegotiate command on the port to which the device is connected OL-27324-02 Release Notes for the Cisco Catalyst Blade Switch 3020 for HP, Cisco IOS Release 15.0(2)SE and Later 13
