Note: at least one autolearned address was skipped because the port with which it is associated has more than 4 autolearned addresses.

If any MAC address was skipped because the concentrator limit was reached, the following message displays upon completion of the Autolearn Download command:

Note: the number of autolearned addresses exceeds the concentrator limit. Only the first X addresses (as ordered by slot, port, and addr) were downloaded.

Where x indicates 360 MAC addresses for an EMM or 400 MAC addresses for TRMM.

Configuring Security Mode

The Security Module provides you with the flexibility of manually enabling or disabling Security Mode for ports. Security Mode is enabled automatically for the ports specified in the SET SECURITY PORT SECURITY_TYPE command.

Issue the following command to enable security for all ports on the Security Module in slot 3.

ONline> set security port 3.all mode enable [ENTER]

Security Type is automatically configured to Full (which includes both Eavesdropping and Intrusion security) when you issue the SET SECURITY PORT MODE ENABLE command.

You may enable Security mode for a port that does not have secure MAC addresses associated with it. However, each packet received by a port will have an invalid MAC address assigned and will therefore be treated as an intrusion.

Note that Security Mode must be disabled in order for the EMM to Autolearn MAC addresses for ports that are configured for Security Types Intrusion or Full. If Security mode is not disabled for each port that is configured for Intrusion Security:
