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.
