Broadcast Packets Received Rate - The total number of packets received rates that were directed
to the broadcast address. Note that this does not include multicast packets.
Discarded Packets Received Rate - The number of inbound packets which were chosen to be
discarded rates even though no errors had been detected to prevent their being deliverable to a
higher-layer protocol. A possible reason for discarding a packet could be to free up buffer space.
Errors Received Rate - The errors received rate of Single, Multiple, and Excessive Collisions.
Unknown Protocols Packets Received Rate - For packet-oriented interfaces, the number of
packets received rates via the interface which were discarded because of an unknown or
unsupported protocol. For character-oriented or fixed-length interfaces that support protocol
multiplexing the number of transmission units received via the interface which were discarded
because of an unknown or unsupported protocol. For any interface that does not support protocol
multiplexing, this counter will always be 0.
Octets Transmitted Rate - The total number of octets transmitted rates out of the interface, including
framing characters.
Unicast Packets Transmitted Rate - The total number of packets rates that higher-level protocols
requested be transmitted to a subnetwork-unicast address, including those that were discarded or not
sent.
Multicast Packets Transmitted Rate - The total number of packets rates that higher-level protocols
requested be transmitted to a Multicast address, including those that were discarded or not sent.
Broadcast Packets Transmitted Rate - The total number of packets rates that higher-level
protocols requested be transmitted to the Broadcast address, including those that were discarded or
not sent.
Discarded Packets Transmitted Rate - The number of outbound packets rates which were chosen
to be discarded even though no errors had been detected to prevent their being deliverable to a
higher-layer protocol. A possible reason for discarding a packet could be to free up buffer space.
Errors Transmitted Rate - The errors transmitted rate of Single, Multiple, and Excessive Collisions.
Time Since Counters Last Cleared - The elapsed time, in days, hours, minutes, and seconds since
the statistics for this port were last cleared.
Command Buttons
Refresh - Refresh the data on the screen with the present state of the data in the switch.
11.2.8 Defining SNMP
11.2.8.1 Configuring SNMP Community Configuration Page
By default, two SNMP Communities exist:
− private, with 'Read/Write' privileges and status set to enable
− public, with 'Read Only' privileges and status set to enable
These are well-known communities, you can use this menu to change the defaults or to add other
communities. Only the communities that you define using this menu will have access to the switch using
the SNMPv1 and SNMPv2c protocols. Only those communities with read-write level access will have
access to this menu via SNMP.
You should use this menu when you are using the SNMPv1 and SNMPv2c protocol: if you want to use
SNMP v3 you should use the User Accounts menu.
