Configuring Etherchannel - Cisco ONS 15454 SDH Configuration Manual

Configuring EtherChannel

Port channel connections are fully compatible with IEEE 802.1Q trunking and routing technologies.
IEEE 802.1Q trunking can carry multiple VLANs across a port channel.
Each ML100T-12, ML100X-8, or ML1000-2 card supports one POS channel, a port channel made up of
the two POS ports. A POS channel combines the two POS port capacities into a maximum aggregate
capacity of STS-48c or VC4-16c.
Each ML100T-12 supports up to six FECs and one POS channel. Each ML100X-8 supports up to four
FECs and one POS channel. A maximum of four Fast Ethernet ports can bundle into one Fast Ethernet
Channel (FEC) and provide bandwidth scalability up to 400-Mbps full-duplex Fast Ethernet.
Each ML1000-2 supports up to two port channels, including the POS channel. A maximum of two
Gigabit Ethernet ports can bundle into one Gigabit Ethernet Channel (FEC) and provide 2-Gbps
full-duplex aggregate capacity on the ML1000-2.
The EtherChannel interface is the Layer 2/Layer 3 interface. Do not enable Layer 3 addresses on the
Caution
physical interfaces. Do not assign bridge groups on the physical interfaces because doing so creates
loops.
Before a physical interface is removed from an EtherChannel (port channel) interface, the physical
Caution
interface must be disabled. To disable a physical interface, use the shutdown command in interface
configuration mode.
Note Link aggregation across multiple ML-Series cards is not supported.
Note Policing is not supported on port channel interfaces.
Note The ML-Series does not support the routing of Subnetwork Access Protocol (SNAP) or Inter-Switch
Link (ISL) encapsulated frames.
Configuring EtherChannel
You can configure an FEC or a GEC by creating an EtherChannel interface (port channel) and assigning
a network IP address. All interfaces that are members of a FEC or a GEC should have the same link
parameters, such as duplex and speed.
To create an EtherChannel interface, perform the following procedure, beginning in global configuration
mode:
