ProSAFE® Intelligent Edge Managed Switches Data Sheet M4300 series Single Rate Policing feature enables support for Single • Committed Information Rate (average allowable rate for the class) Rate Policer as defined by RFC 2697 • Committed Burst Size (maximum amount of contiguous packets for the class) • Excessive Burst Size (additional burst size for the class with credits refill at a slower rate than committed burst size) • DiffServ feature applied to class maps Automatic Voice over IP prioritization with protocol-based (SIP, H323 and SCCP ) or OUI-based Auto-VoIP up to 144 simultaneous voice calls iSCSI Flow Acceleration and automatic protection / QoS with Auto-iSCSI Flow Control 802.3x Flow Control implementation per IEEE 802.3 Annex 31B specifications with Symmetric flow control, Asymmetric flow control or No flow control • Asymmetric flow control allows the switch to respond to received PAUSE frames, but the ports cannot generate PAUSE frames • Symmetric flow control allows the switch to both respond to, and generate MAC control PAUSE frames Allows traffic from one device to be throttled for a specified period of time: a device that wishes to inhibit transmission of data frames from another device on the LAN transmits a PAUSE frame • A device that wishes to inhibit transmission of data frames from another device on the LAN transmits a PAUSE frame UDLD Support UDLD implementation detects unidirectional links physical ports (UDLD must be enabled on both sides of the link in order to detect an unidirectional link) • UDLD protocol operates by exchanging packets containing information about neighboring devices • The purpose is to detect and avoid unidirectional link forwarding anomalies in a Layer 2 communication channel Both "normal-mode" and "aggressive-mode" are supported for perfect compatibility with other vendors implementations, including port "D-Disable" triggering cases in both modes M4300-8X8F M4300-12X12F M4300-24X24F M4300-28G M4300-52G M4300-28G-PoE+ M4300-52G-PoE+ M4300-24X M4300-48X Page 13 of 49 M4300-24X M4300-48X M4300-8X8F M4300-12X12F M4300-24X24F M4300-28G M4300-52G M4300-28G-PoE+ M4300-52G-PoE+
