<b>failover</b><br/>
|
|
150
|
Sends and receives traffic only through the master port. If
|
|
151
|
the master port becomes unavailable, the next active port is
|
|
152
|
used. The first interface added is the master port; any

153
|
interfaces added after that are used as failover devices.
|
|
154
|
</li><li>
|
|
155
|
<b>fec</b><br/> Supports Cisco EtherChannel. This is a static setup and
|
|
156
|
does not negotiate aggregation with the peer or exchange
|
|
157
|
frames to monitor the link.
|
|
158
|
</li><li>
|
|
159
|
<b>lacp</b><br/> Supports the IEEE 802.3ad Link Aggregation Control Protocol
|
|
160
|
(LACP) and the Marker Protocol. LACP will negotiate a set
|
|
161
|
of aggregable links with the peer in to one or more Link
|
|
162
|
Aggregated Groups. Each LAG is composed of ports of the
|
|
163
|
same speed, set to full-duplex operation. The traffic will
|
|
164
|
be balanced across the ports in the LAG with the greatest
|
|
165
|
total speed, in most cases there will only be one LAG which
|
|
166
|
contains all ports. In the event of changes in physical
|
|
167
|
connectivity, Link Aggregation will quickly converge to a
|
|
168
|
new configuration.
|
|
169
|
</li><li>
|
|
170
|
<b>loadbalance</b><br/> Balances outgoing traffic across the active ports based on
|
|
171
|
hashed protocol header information and accepts incoming
|
|
172
|
traffic from any active port. This is a static setup and
|
|
173
|
does not negotiate aggregation with the peer or exchange
|
|
174
|
frames to monitor the link. The hash includes the Ethernet
|
|
175
|
source and destination address, and, if available, the VLAN
|
|
176
|
tag, and the IP source and destination address.
|
|
177
|
</li><li>
|
|
178
|
<b>roundrobin</b><br/> Distributes outgoing traffic using a round-robin scheduler
|
|
179
|
through all active ports and accepts incoming traffic from
|
|
180
|
any active port.
|
|
181
|
</li><li>
|

<b>none</b><br/> This protocol is intended to do nothing: it disables any
|
|
183
|
traffic without disabling the lagg interface itself.
