8-2 Set ETH Function
GGS-000547-01E iPASOLINK EX Advanced: SET NETWORK AND SYSTEM PROVISIONING
Users can set the priority of the bridge; specify the role of the Ethernet port and
other parameters.
MSTP Setting (
MSTP Port)
MSTP (Multiple Spanning-Tree Protocol) defined by the IEEE802.1s is the
spanning-tree protocol working with the logical instances. One instance can include
multiple VLANs. Blocking port is decided per logical instance, and then physically
configured redundant Ethernet Topology can be utilized efficiently.
In addition to the standard MSTP features, iPASOLINK supports the root-guard
feature that prevents an unexpected node being the root node, and the BPDU-guard
feature that discards a BPDU frame if it arrives.
NOTE: MSTP and ERP do not operate simultaneously at the same
equipment.
ERP Setting
High-speed protection switch and load balancing are realized by G.8032 Ethernet
Ring Protection. The maintenance can be done with minimum service affecting by
the administrative operation, such as manual/forced switching.
Load balancing works under the normal operation, and the higher priority traffic
can be secured by QoS management.
Fast Switch-over (<50ms) with 3.3ms period, hardware based ETH-CC.
Administrative operation:
– Forced switching
– Manual switching
– Multi-Ring
– Revertive / Non-revertive
The combination of logical ring set-up and load balancing achieves double capacity
transmission.
Link Aggregation
Link Aggregation achieves high capacity and resiliency transport with bundling
several radio links. The distribution algorithm distributes the packet according to:
L2 based: Source & Destination MAC, VLAN ID, Ethernet type, Physical Port
ID.
L3&L4 based: Source & Destination IP, Source & Destination TCP/UDP Port
Number
MPLS label based: Tunnel Label & VC Label
Also, ETH Ports support Both of LACP and Non-LACP operation with carrier class
1:1 LACP Protection.
