Status:
Fixed
Severity:
2 Severe
Description:
Symptom: when we power off/on 3750X-12S stack master and one member and two other switches which are connected with this stack at the same time, after they boot up, ping going through this 3750X stack new master is NG.
Conditions: (1)power off/on 3750X-12S stack master and one member and two other switches which are connected with this stack at the same time (2)ping going through new master

Symptom: Static SGACL permissions are not updated for authentication server assigned SGT. Conditions: This symptom is seen with an authentication server assigned SGT. Workaround: Use manual SGT or dynamic SGACL.
CTS C3KX-SM to N7K in LACP Link down after ~9 master switchover
Status:
Fixed
Severity:
2 Severe
Description:
Symptom: After a master switchover in a 3750X stack C3KX-SM module port-channels to the neighboring N7K enter into "suspended" state on the N7K side. Interfaces remain suspended even after the original master switch returns to service. The link state is up/down in the 3750X switch. This happens intermittently after a lot of master switch overs. Conditions: This issue is seen with C3KX-SM module interfaces configured in MACSEC CTS manual mode with SAP GCM Encrypt encapsulation. Workaround: Shut/No Shut on the affected port.
Shutdown is displayed with linkup channel member port on show run.
Status:
Fixed
Severity:
3 Moderate
Description:
Symptom: Shutdown command is displayed on channel member port. However, channel member port is linkup status. This issue is seen after shut/no shut on channel port.
Conditions: 3750X Ether-Channel connection.
Workaround: 'no shutdown' command on channel member port.

Description:
Symptom: %SFF8472-5-THRESHOLD_VIOLATION message is seen on 3750X sfp port even there is no cable inserted into that port or the connected device is down

CSCux680233750 :: stale entry present in mac address table
Status: *
Terminated
Severity:
3 Moderate
Description:
Symptom: 3750 switch has a stale entry present in mac address table
problematic MAC is marked as static and there is no way of clearing it other than device reload.
Following tests were done in order to remove the mac: - port shut/no shut, - removing single features from the port (eg. port security), - defaulting interface config, - attempt to configure similar static entry (same mac, vlan, port) - attempt to configure similar static entry (same mac, vlan, different port) - configured "authentication timer inactivity 10",
Conditions: Interface where stale MAC is pointing is configured with multiple features: - port security, - dot1x - mab
Workaround: Reload the device to clear the MAC
Further Problem Description: At this point in time trigger for the issue is not know and no business impact was observed. Other devices connected to port where stale mac is pointing work fine
Symptom: After switchover, CTS triggers the SAP Rekey. The New Master has different MAC address so rekey fails. Therefore to maintain the SAP Session after switchover. CTS needs to sync the MAC address.
Conditions: Sync the SAP Session MAC address to the member. To maintain SAP Session after switchover rekey.
Workaround: Shut / no shut the interface after switchover.
PLATFORM_STACKPOWER-4-UNBALANCED_PS: Switch 1's power stack has unbalanc
Status:
Fixed
Severity:
3 Moderate
Description: *
Symptom: In some power stack scenarios, when removing a unit from the power stack, a unit in the remaining power stack may incorrectly report this error.
Conditions: For this case, there is a power stack of 4. Each unit has 2 supplies except for unit 4 which has 1 supply. When unit 4 is removed from the power stack, unit 1 incorrectly reports the unbalanced power stack error.
Workaround: You can toggle the stack ports (shut/no shut) on the unit that is incorrectly reporting this error. config t stack-power switch standalone no standalone
3750X: Log messages to report misconfiguration with Redirect ACL
Status:
Fixed
Severity:
6 Enhancement
Description:
Symptom: Catalyst 3750X CPU utilization may intermittently spikes due to EPM MAIN PROCESS, when the redirect ACL has an Access-list Entry (ACE) with source part not "any".
Under this condition, programming the dACL into the hardware fails and dACL is downloaded again to re-program.
3750X#show process cpu sorted CPU utilization for five seconds: 97%/2%; one minute: 96%; five minutes: 94% PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process 311 3168483 177598 17840 27.43% 8.75% 7.95% 0 EPM MAIN PROCESS
Conditions: Seen in Catalyst 3750X running 15.0(2)SE4 release.
Workaround: Remove the ACE with wrong configurations.
This bug is an enhancement request to generate a log message (which will be rate-limited) to indicate misconfiguration(s).
