Network Connectivity Checks

This table lists and describes steps to take to check network connectivity.

Step Command Expected Behavior
Verify basic network reachability ping <device-ip> from Management Cloud Engine (MCE) server Successful ping response
Verify SSH connectivity ssh <user@device-ip> from MCE server Able to connect and authenticate
Verify SFTP connectivity sftp <user@device-ip> from MCE server Able to establish connection
Verify SNMP connection from MCE server
  • For v1v2:
     snmpbulkget <device ip> -v 2c -c <community-string> 1.3.6.1.2.1.1.2
  • For v3:
     snmpbulkget -v3 -u <username> -l authPriv -a SHA256 -A <auth-password> -x AES128 -X <priv-password> <device-ip> 1.3.6.1.2.1.1.2
  • If there is no snmp-utils installed, try installing on a Linux system with:
    sudo yum install net-snmp-utils
  • Verify SNMPv3 related configurations to connect to the device using SNMPv3 protocol using the following procedure:
    1. Navigate to system, snmp-address-entry and ensure the address field contains the LAN IP address of the MCE server.
    2. Navigate to system, snmp-user-entry and select the user entry that will be used for authentication with Oracle SDM Cloud. Note that the required SNMPv3 username is operuserp(this must be used when adding the device to Oracle SDM Cloud.
    3. Verify that the address-list field references the correct address entry (the one with the MCE server’s IP address, set in step 1).
    4. Check system, system-config, snmp-agent-mode and confirm it is set to v3.
    5. Perform a Save and Activate config and reboot the device.
    6. Add the device to the Oracle SDM Cloud using the SNMPv3 credentials.
      If the device is not added, run the following command on the MCE server CLI to see if the device is accessible using SNMPv3.
      snmpbulkget -v3 -u <user-name> -l authPriv -a SHA256 -A <auth-password> -x AES128 -X <priv-password> <device-ip> 1.3.6.1.2.1.1.2
  
Check the firewall sudo iptables -L -n -v

or

sudo firewall-cmd --list-all
