Chapter 6 Tool Table 49 Tool > Auto-Discovery (continued) LABEL DESCRIPTION Net Mask This field displays the subnet mask of the IP address(es). Start IP This field is available if you select IP Range in the Discover Type field. This field displays the starting IP address of the IP range. End IP This field is available if you select IP Range in the Discover Type field. This field displays the ending IP address of the IP range. SNMP SNMP Version Select the version of the SNMP poll messages the ENC sends in order to communicate with managed devices. You can select more than one check box if your devices support different SNMP versions. SNMP Port Enter the port number the ENC uses to transmit and receive SNMP messages to/from managed devices. Read Community Type the read-only community string the ENC uses to view information on managed devices. User Name This field is available if you selected v3 in the SNMP Version field. Context Name Enter the user name of the administrator account on the device. This field is available if you selected v3 in the SNMP Version field. Authentication Enter the context name configured in the device that you are looking for. This field is available if you selected v3 in the SNMP Version field. Auth. Password Select which hash algorithm (MD5 or SHA1) to use to authenticate SNMP packets transmitted between the ENC and the device. SHA1 is generally considered stronger than MD5, but it is also slower. Select None if no authentication is required. This field is available if you selected MD5 or SHA1 in the Authentication field. Enter the authentication key, which depends on the authentication algorithm you selected. MD5 - a key 16-20 characters long SHA1 - a key 20 characters long Privacy You can use any alphanumeric characters or If you want to enter the key in hexadecimal, type "0x" at the beginning of the key. For example, "0x0123456789ABCDEF" is in hexadecimal format; "0123456789ABCDEF" is in ASCII format. This field is available if you selected MD5 or SHA1 in the Authentication field. Select which encryption algorithm to use for SNMP packets transmitted between the ENC and the device. None - no encryption key or algorithm DES - a 56-bit key with the DES encryption algorithm Privacy Password AES - a 128-bit key with the AES encryption algorithm This field is available if you selected DES or AES in the Privacy field. Polling Enable Status Polling Polling Interval Enable autoremove obsolete devices Enter the encryption key with the length according to the Privacy setting. Select this to have the ENC poll its managed devices periodically to update their status in the ENC. Clear this to disable it. Select how often in minutes the ENC sends a poll message to a managed device. Select this to allow a device to remain offline for the specified number of days before the ENC removes it from the OTV panel. You can configure the days in the Auto remove after offline period field. Clear this if you want to disable this feature. 138 ENC User's Guide
