The IMS-CPU runs Meinberg’s all new LTOS V7 firmware generation with an incredible feature set. The V7 network concept allows to configure up to 99 logical network interfaces and assign them to one of the physical network ports or a link aggregation group. Network services like HTTP, SSH or NTP can be individually enabled/disabled for each virtual interface. Each CPU can manage up to 99 physical ports in theory and offers enterprise features like VLAN (IEEE 802.1Q), QoS/traffic priorization (DSCP and IEEE802.1p) as well as full IPv6 support. The powerful web based configuration interface provides access to all important LTOS V7 parameters and functions. Multiple firmware versions can be installed on one unit, making it easy to try out new versions and roll back to a previous version with one mouse click. Backing up system configuration is easier than ever with the V7 capability to store multiple revisions of the configuration on a unit and offer different ways to upload and download configuration sets.
The web GUI, accessible using both HTTP and HTTPS, is accompanied by the command line interface (CLI). Administrators can log in via SSH, Telnet or the serial console port and, with the appropriate access level, will find a standard shell environment with full script support and hundreds of well known Unix commands. A full featured SNMP management service supporting SNMP V1, V2c and V3 (auth and privacy) including a large selection of standard MIBs and a Meinberg specific enterprise MIB offers a proven way to integrate the system into an existing network management system. A USB port allows to backup/restore configuration sets using a USB memory stick and can be used to install a new firmware version on the device. If required, both the USB port and the access to the LC menu can be disabled.
