Known Issues and Limitations
| Bug ID |
Description |
| If a EOR gets stuck while configuring monitor scale at flow system configuration, try the following workaround: - Save current running config to bootflash, other local file system or USB. - Reload ascii - Reload switch. - Do a SUP system switchover (SSO). |
|
| When you remove template peer-policy under l2vpn EVPN address-family it deletes the prefixes. The workaround is to reconfigure the affected neighbor or restart BGP. |
|
| VLAN Mapping: strict incompatibility during downgrade from 10.3.x to 9.3.x. |
|
| If a single mac address moves more than 10 times in a second, then mac learning would be disabled on corresponding vlan for 120 seconds. This is a known limitation. |
|
| On Cisco Nexus N2K-C2348TQ HIFs fail to utilize redundant Port-Channel links, to NIF, during link failover events. |
|
| DSA, a weaker cryptographic algorithm is disabled by default in CiscoSSH |

aFor specific fan speeds see the Overview section of the Hardware Installation Guide.
b This switch runs with +1 redundancy mode so that if one fan fails, the switch can sustain operation. But if a second fan fails, this switch is not designed to sustain operation. Hence before waiting for the major threshold temperature to be hit, the switch will power down due to entering the fan policy trigger command.
