Interfaces Monitoring

MegaVision provides extensive monitoring performance of any SNMP devices interfaces, whether they belong to the supported set of devices or not. Interfaces monitoring may be accessed through the Monitor menu item on the main menu bar. The various options will be described below.

Interfaces Table Window

Enter this window via Monitor/Interfaces Table in the main menu bar or by clicking the Interfaces Table button in the Identify Window. The Interfaces Table window displays information about a device’s interfaces. It based on the information from the ifTab (RFC1213, MIB-II). Any SNMP-compliant device must support Interfaces Table.

Figure 21. Interfaces Table.

Below is a list of information presented in the Interfaces Table, regardless of the interface type:

Interface Number – number of interface (corresponds to ifIndex from MIB-2)

Interface Description - a textual string containing information about the interface.

Interface Type - the type of interface, distinguished according to the physical/link protocol(s) immediately ‘'below' the network layer in the protocol stack.

Interface Speed - an interface's current bandwidth in bits per second. For interfaces, which do not vary in bandwidth, or for those where no accurate estimation can be made, this object should contain the nominal bandwidth.

MAC Address - the interface's address at the protocol layer immediately ‘below’ the network layer in the protocol stack. For interfaces, which do not have such an address (e.g., a serial line), this object should contain an octet string of zero length. If the address does not have an alias, then the raw address will be displayed. Otherwise, the current alias name will be displayed. The user may add/edit aliases via the ARP Add/Edit window, Alias Manager Window, or other windows, which allow aliases editing.
