Summary

The Cloud Router Switch series are highly integrated switches with high performance ARM CPU and feature-rich packet processor. The CRS switches can be designed into various Ethernet applications including unmanaged switch, Layer 2 managed switch, carrier switch and wired unified packet processing.

Warning: This article applies to CRS3xx series switches and not to CRS1xx/CRS2xx series switches.


FeaturesDescription
Forwarding
  • Configurable ports for switching or routing
  • Full non-blocking wirespeed switching
  • Up to 16k MAC entries in Unicast FDB for Layer 2 unicast forwarding
  • Up to 1k MAC entries in Multicast FDB for multicast forwarding
  • Up to 256 MAC entries in Reserved FDB for control and management purposes
  • All Forwarding Databases support IVL and SVL
  • Configurable Port based MAC learning limit
  • Jumbo frame support
Mirroring
  • Various types of mirroring:
    • Port based mirroring
    • VLAN based mirroring
    • MAC based mirroring
  • 2 independent mirroring analyzer ports
VLAN
  • Fully compatible with IEEE802.1Q and IEEE802.1ad VLAN
  • 4k active VLANs
  • Flexible VLAN assignment:
    • Port based VLAN
  • VLAN filtering

This table clarifies main differences between Cloud Router Switch models.

Model Switch Chip CPU Wireless SFP+ port Access Control List Jumbo Frame (Bytes)
