Instance Method Details

#add_member(name, member) ⇒ Boolean

add_member adds the interface specified in member to the port-channel interface specified by name in the nodes running-configuration. If the port-channel interface does not already exist, it will be created.

def add_member(name, member)
  lacp = parse_lacp_mode(name)[:lacp_mode]
  grpid = /(\d+)/.match(name)[0]
  configure ["interface #{member}", "channel-group #{grpid} mode #{lacp}"]
end

#get(name) ⇒ nil, Hash<Symbol, Object>

get returns the specified port-channel interface configuration from the nodes running configuration as a resource hash. The resource hash returned extends the BaseInterface resource hash, sets the type value to portchannel and adds the portchannel specific attributes

Examples:

{
  type: 'portchannel'
  description: <string>
  shutdown: [true, false]
  members: array[<strings>]
  lacp_mode: [active, passive, on]
  minimum_links: <string>
  lacp_timeout: <string>
  lacp_fallback: [static, individual, disabled]
}

#remove_member(name, member) ⇒ Boolean

remove_member removes the interface specified in member from the port-channel interface specified by name in the nodes running-configuration.

end

#set_lacp_fallback(name, opts = {}) ⇒ Boolean

set_lacp_fallback configures the lacp fallback mode for the port-channel interface. If no value is provided, lacp fallback is configured using the no keyword argument. If the default option is specified and set to true, the lacp fallback value is configured using the default keyword. The default keyword takes precedence over the value keyword if both options are provided.

end

#set_lacp_mode(name, mode) ⇒ Boolean

set_lacp_mode configures the lacp mode on the port-channel interface by configuring the lacp mode value for each member interface. This method will find all member interfaces for a port-channel and reconfigure them using the mode argument.

end

#set_lacp_timeout(name, opts = {}) ⇒ Boolean

set_lacp_timeout configures the lacp fallback timeou for the port-channel interface. If no value is provided, lacp fallback timeout is configured using the no keyword argument. If the default option is specified and set to true, the lacp fallback timeout value is configured using the default keyword. The default keyword takes precedence over the value keyword if both options are provided.

end

#set_members(name, members) ⇒ Boolean

set_members configures the set of physical interfaces that comprise the logical port-channel interface. The members value passed should be an array of physical interface names that comprise the port-channel interface. This method will add and remove individual members as required to sync the provided members array

end

#set_minimum_links(name, opts = {}) ⇒ Boolean

set_minimum_links configures the minimum physical links up required to consider the logical portchannel interface operationally up. If no value is provided then the minimum-links is configured using the no keyword argument. If the default keyword argument is provided and set to true, the minimum-links value is defaulted using the default keyword. The default keyword takes precedence over the value keyword argument if both are provided.
