Release Notes for the Cisco Catalyst Blade Switch 3020 for HP, Cisco IOS Release 15.0(2)SE and Later
16
CSCts95370
If an ACL is configured on a router VTY line for ingress traffic, the ACL is applied for egress traffic
also. As a result, egress traffic to another router on an SSH connection is blocked.
The workaround is to permit egress traffic to the specific destination router using the permit tcp
host <destination router IP address> eq 0 any interface configuration command.
CSCub85948
Memory leak is seen in the switch when it sends CDP, LLDP or DHCP traffic and when the link
flaps.
The workaround is to apply protocol filters to the device sensor output by entering the following
global configuration commands:
no macro auto monitor
device-sensor filter-spec dhcp exclude all
device-sensor filter-spec lldp exclude all
device-sensor filter-spec cdp exclude all
If the memory leak continues in the "DHCPD Receive" process, disable the built-in DHCP server
by entering the no service dhcp global configuration command.
CSCuc40634
STP loop occurs on Flexstack connected by parallel links when a link state is changed on Flexlink
port.
The workaround is to change the switch to root bridge.
CSCud83248
When native VLAN is configured on the trunk or when switchport trunk native vlan 99 is configured
on the interface, spanning-tree instance is not created for native VLAN.
The workaround is to keep VLAN1 as a native on the trunk. In Cisco IOS Release15.0(2) SE, dot1.x
is enabled by default and causes authentication fail in the native VLAN. This results in
pm_vp_statemachine not triggering any event to spanning tree. To disable dot1x internally, run
the no macro auto monitor command. The stp instance is created for native vlan 99 after running
the show and no show command on the interface.
CSCue87815
When the secret password is configured, the password is not saved. The default password is used as
the secret password.
The workaround is to use the default password to login and then change the password.
CSCee32792
When using SNMP v3, the switch unexpectedly reloads when it encounters the
snmp_free_variable_element.
There is no workaround.
CSCth03648
When two traps are generated by two separate processes, the switch fails if one process is suspended
while the other process updates variables used by the first process.
