XL mode enables a larger forwarding table (up to 1 million IPv4 routes or 350,000 IPv6 routes), providing investment protection through increased system flexibility and ease of sparing
The comprehensive set of Layer 2 and Layer 3 functions makes this module ideal for data center networks
Virtual output queuing (VOQ) with centralized arbitration - VOQ enables fairness when one or more destinations are congested and supports lossless unified fabric
Load sharing across all fabric modules - through its high-availability design, bandwidth is shared across all fabric modules simultaneously for optimal performance
Distributed forwarding - through its fully distributed data plane, the module offers high-performance parallel forwarding
Multiprotocol Label Switching (MPLS) - supports MPLS forwarding in hardware
IEEE 1588 PTP - the module supports Precision Time Protocol (PTP) based on IEEE 1588
Identification (ID) LED - through the beacon feature, administrators can clearly identify the module for a service condition; ports on the I/O module can send beacons as well
