HP Cisco Catalyst Blade Switch 3020 Release Notes for the Cisco Catalyst Blade - Page 16

Caveats Resolved in Cisco IOS Release 15.0(2)SE1, no service dhcp - for default password

Page 16 highlights

Resolved Caveats • 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 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. Caveats Resolved in Cisco IOS Release 15.0(2)SE1 • 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.

Release Notes for the Cisco Catalyst Blade Switch 3020 for HP, Cisco IOS Release 15.0(2)SE and Later
OL-27324-02
Resolved Caveats
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.
Caveats Resolved in Cisco IOS Release 15.0(2)SE1
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.
