Link Layer Discovery Protocol (LLDP)
The IEEE 802.1AB standard defines the Link Layer Discovery Protocol (LLDP). This protocol allows a
switch residing on an 802 VLAN to advertise connectivity, physical description, management information,
and major capabilities. The information distributed via this protocol is stored by its recipients in a standard
Management Information Base (MIB), facilitating multi-vendor interoperability and use of standard
management tools to discover and make available physical topology information for network management.
The command set includes:
• Configure LLDP globally (Global Config mode):
—[
no] lldp {[mode {tx | rx | both}] [hello seconds] [multiplier integer]}
Enter either
mode, hello, or multiplier, followed by a value for the associated variable.
• Configure LLDP on a single port (timers not supported on one interface) (Interface Config mode):
—[
no] lldp mode {tx | rx | both}
• Display LLDP information (Privileged Config mode):
show lldp interface [all | interface unit/slot/port]
show lldp local-device [all | interface unit/slot/port]
show lldp neighbors [all | interface unit/slot/port]
show lldp remote-device [all | interface unit/slot/port]
• Clear LLDP information (Global Config mode):
clear lldp neighbors [interface unit/slot/port]
clear lldp counters [interface unit/slot/port]
Setting up Remote Network Monitoring (RMON)
Remote Network Monitoring (RMON) in SFTOS is based on industry RMON RFC standards, providing
both 32-bit and 64-bit monitoring of S-Series switches, along with long-term statistics collection.
RMON is an extension of SNMP, and requires an agent to be running on the devices to be monitored. The
SFTOS implementation of RMON allows the user to configure alarms and events (actions: enter log entry
or send trap).
SFTOS supports the following RMON MIB groups defined in RFC-2819, RFC-3273, and RFC-3434:
Statistics
(OID 1.3.6.1.2.1.16.1)
Contains statistics measured by the probe for each monitored interface on this device —
packets dropped, packets sent, bytes sent (octets), broadcast packets, multicast packets,
CRC errors, runts, giants, fragments, jabbers, collisions, and counters for packets ranging
from 64 to 128, 128to 256, 256 to 512, 512 to 1024, and 1024 to 1518 bytes.
History
(OID 1.3.6.1.2.1.16.2)
Records periodic statistical samples from a network and stores for retrieval — sample
period, number of samples, items sampled.
