Cisco Cisco Packet Data Gateway (PDG)
Specifies that a Link Aggregation Group (LAG) is up /usable only when a minimum number of links are
available for aggregation. This guarantees that a minimum amount of bandwidth is available for use.
available for aggregation. This guarantees that a minimum amount of bandwidth is available for use.
number_links specifies the minimum number of links required to avoid a LAG switchover as an integer from
1 through 255.
1 through 255.
When this feature is enabled, a LAG is not usable when the number of links in a LAG goes below the configured
min-link value. Switchover to another LAG bundle (if available) automatically occurs when the number of
links in the current active bundle goes below the configured min-link value.

mode { non-redundant | redundant }
This feature is only supported on the ASR 5500.
Important
Specifies whether the LAG is configured in non-redundant (Active-Active mode) or redundant (Active-Standby)
mode.

redundancy { standard | switched } [ hold-time sec ] [ preferred slot { card_number | none } ]
Connects top and bottom ASR 5000 QGLCs, side-by-side ASR 5000 XGLCs cards, or ASR 5500 MIOs to
different Ethernet switches. The master port must be set to make this effective for the group.
different Ethernet switches. The 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.
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.
• XGLC (ASR 5000) – the preferred slot is selected for the initial timeout period to make the selection
of an Ethernet switch less random.
• MIO (ASR 5500) – the preferred slot is selected for the initial timeout period to make the selection of
an Ethernet switch less random.
none: Specifies no preferred slot.
toggle-link
The toggle-link keyword is not supported on the ASR 5500.
Important
Set to toggle link on port switch.
