Table 10-14 LAG <lag-index> [SHOW] Command Output
Command
Parameter Output Description
LACP Mode The Link Aggregation Control Protocol (LACP) is automatically set to Static by
default.
The Static LACP Mode does not require the Packet Voice Processor to negotiate
with other partner devices that are connected to the Packet Voice Processor for
determining the LAG port state within the LAG. For additional information about
Static LACP Mode, see
Section 6.2.2 on page 60 .
Key The Key value is a user selected number that identifies the Link Aggregation
Group (LAG) across the network.
MAC Address The MAC (Media Access Control) address is a unique value associated with a
LAG interface on the network. This is a logical value associated with the IP
address provisioned on the LAG interface, and not a physical value.
Next Hop Device IP
(for link
redundancy) The Next Hop Device IP configuration supports a required media network
interface redundancy for the LACP Static mode.
The Next Hop Device IP value is the IP address of a third-party device connected
in the same IP subnet as the LAG interface on the PVP, that the PVP immediately
receives/sends the RTP packets from/to. The third-party device can be a Session
Border Controller (SBC) or a router that supports VRRP or HSRP like redundancy.
LAG IPs Name - User created index number.
Address - IP address for the LAG.
Mask - IP Subnet Mask address for the LAG.
Minimum UDP Ports - Minimum number of UDP ports used for the LAG.
Maximum UDP Ports - Maximum number of UDP ports used for the LAG.
LAG Ports -
Name
Physical port name and location.
The first number after “GigE/” describes the shelf slot and the second number
describes the location of the port read from the top of the Interface Processing
card to the bottom of the Interface Processing card.
LAG Ports -
State
State - Active, Inactive, or Standby
The LAG port state is determined to be Active, Inactive, or Standby based upon
the following considerations:
• Physical connectivity to the partner device.
• Redundancy role assigned to the port using the PVP CLI (Master or Backup)
• IP connectivity to the next-hop media device from the LAG port
For additional information, see
Section 6.2 on page 60 .
A LAG must have at least 1 active LAG port for the transmitting and receiving IP
packets on the LAG interface.
LAG Ports -
Role
Role: Master or Backup
Master and Back-up roles are defined similarly as in the VRRP standard. On the
Packet Voice Processor, the LAG port configured with the "Master" redundancy
role will have greater priority than the LAG port configured with "Back-up" port (see
Section 10.6.18, “LAG <lag-index> PORT ADD <avl-media-port> [red-role]
Command”, on page 148
).
"Master" and "Back-up" ports will alternatively move in active state (assuming that
the connections remain up). The alternative ports are set to standby state. The
switch-over occurs when the connectivity to the Next Hop Device IP (for link
redundancy) is lost on the current all active port(s).
