lacp { active | passive }
Configures the Link Aggregation Control Protocol (LACP). Set this option on the master port for use with the
whole group.
whole group.
active
mode sends out LACP packets periodically. (Default)
passive
mode only responds to LACP packets received.
rate { auto | fast | slow }
Configures the rate at which the LACP sends packets.
auto
: rate is controlled by the peer
fast
: 1 seconds
slow
: 30 seconds (Default) [ASR 5000 only]
timeout { long | short }
Configures LACP timeout events. Set this option on the master port for use with the whole group.
long
: Set LACP to long timeout
short
: Set LACP to short timeout
master { global group group_number | group group_number | local group
group_number }
group_number }
This command creates the Master port for the aggregated group.
global
: Set group global across slots.
group group_number
: Set link aggregation group number.
group_number
must be an integer between 1
and 1023.
local
: Set group local within same slot.
member { global group group_number | group group_number | local group
group_number }
group_number }
This command makes the port a member of the aggregated group.
global
: Set group global across slots.
group group_number
: Set link aggregation group number.
group_number
must be an integer from 1
through 1023.
local
: Set group local within same slot.
redundancy { standard | switched } [ hold-time sec ] [ preferred slot {
card_number | none } ]
card_number | none } ]
Connects top and bottom QGLCs, side-by-side XGLCs, or MIO cards, to different Ethernet switches. The
master port must be set to make this effective for the group.
master port must be set to make this effective for the group.
standard
: Treats all cards in the group as one group. (Default)
switched
: Assumes cards are connected to different switches. [ASR 5000 only]
hold-time sec
: Sets the amount of time to hold (in seconds) before switching between cards. Applies to
standard and switched modes.
sec
must be an integer from 0 through 3600. Default: 10
preferred slot {
card_number
| none }
: Specifies the preferred behavior for a LAG using two
Ethernet switches. Applies to standard and switched modes.
card_number
is an integer between 1 and 48 on
an ASR 5000, or 5 or 6 on an ASR 5500.
When a card number is specified, system behavior varies based on the card type.

QGLC (ASR 5000) – the preferred slot is selected only when both the top and bottom slots have the
same number of active LACP ports.
