418 Configuring Switching Information
The Group Configuration Summary
page contains the following fields:
•
Group ID
— Identifies the aggregator group.
•
VLAN
— Select the VLAN or VLANs that will have the Aggregator Group as a member. An Aggregator
Group can be a member of multiple VLANs, but each VLAN can only belong to one Aggregator Group.
By default, a VLAN is reserved for each group, starting with VLAN 4022 for group 1. The reserved
VLAN cannot be deleted from the group, but you can configure the group to participate in additional
unreserved VLANs.
•
LACP Mode —
Identifies the LACP mode for the aggregator group. The available options are Auto,
Static, or Off:
–
Auto
— External ports are automatically configured as a LACP trunk group. External switches
must support LACP if multiple external ports are members of this Aggregator Group. Uplink ports
in the Aggregator Group receive LACP PDUs, listen for the LACPDUs from the partner, and
negotiate the Link Aggregation. External (uplink) ports will be re-enabled once LACP is detected
on the active uplink without user intervention.
– Static — The uplink ports in the Aggregator Group are set to Static mode. Static LAGs are
recommended when connecting the PowerConnect M6220/M6348/M8024 switch to an external
Ethernet switch that does not support LACP.
–
Off
— Link Aggregation is off, and the aggregator group has only one uplink port. This mode
avoids any possible loops in the network.
•
Min. Uplinks
— Identifies the minimum number of external (uplink) ports to be active in order for
the Aggregation Group to be active. For example, when a switch has two external ports in the group
and four internal ports, if the minimum active uplink ports is two, then both external ports must be
active; otherwise, all the internal ports in the aggregator group will be brought DOWN. By default, the
minimum active uplinks for an Aggregator Group is 1, which means at least one uplink port should be
active for the Aggregator Group to be active.
•
MTU Mode
— Shows whether support for jumbo frames is enabled or disabled. Jumbo frames enables
transporting identical data in fewer frames to ensure less overhead, lower processing time, and fewer
interrupts.
•
Negotiation
— Shows whether Auto Negotiation is enabled or disabled on the group. Auto
Negotiation is a protocol between two link partners that enables a port to advertise its transmission
rate, duplex mode and flow control abilities to its partner.
•
Speed
— Identifies the port speed to be advertised by the ports in the group. If the speed is not
supported by a port in the group, the port will ignore the speed and transmit data at the last successful
speed setting. The possible field values are:
–
10
— Indicates that the valid ports in the group advertise a 10 Mbps data rate.
–
100
— Indicates that the valid ports in the group advertise a 100 Mbps data rate.
–
1000
— Indicates that the valid ports in the group advertise a 1000 Mbps data rate.
–
10000
— Indicates that the valid ports in the group advertise a 10000 Mbps data rate.
