TitlePort goes into the Disabled state after a period of time
Port goes to the disabled state. 
Status of the port: 
Slot-1 SW1 # sh port 1:25 no-refresh
Port Summary
Port  Display         VLAN Name          Port  Link  Speed  Duplex
#     String          (or # VLANs)       State State Actual Actual
1:25                  (0005)              D     R  D
This is an expected output with ELSM enabled and the port  is administratively disabled.
Exos All
Summit and Blackdiamond Series
The port will be administratively disabled only under two conditions. 

- When the "disable port <port number>" is executed via CLI or via script.
- When SNMP set is received by the switch with an OID to disable the port. 
To identify if the port is disabled via CLI, we can enable the following command: 
enable cli-config-logging
This will log a message if the command was executed along with the user name under which the command was executed.

To identify if the port is disabled because of the SNMP set, please check if SNMP set counters increases in the "show management" output.

It is recommended to configure the SNMP access profile to restrict the SNMP access to the switch. Please refer the article below for more information about access-profile. 

How to restrict SNMP access

To identify the source of the SNMP set, we need to do a packet capture of the packets hitting the CPU. Refer the article below or contact GTAC for more information on this.
