WebMarking Ethernet frames is accomplished using the 3-bit 802.1p Class of Service (CoS) field. The CoS field is part of the 4-byte 802.1Q field in an Ethernet header, and thus is only available when 802.1Q VLAN frame tagging is employed. The CoS field provides 8 priority values: Type Decimal Binary General Application Routine 0 000 Best effort ... WebMay 14, 2013 · If you need CoS tagging, it might be possible with a Ethernet switch module in an ISR or you might need a smart switch, in between the router and the MetroSwitch (assuming you can't manage the latter). If fact, if your LAN switch has available ports and capability needed, you might loop back your router's "TRUNK" link though it.
WebThe maximum Ethernet frame rate is achieved by a single transmitting node that does not suffer any collisions when Ethernet frames are at their smallest size. The minimum Ethernet frame payload is 46 bytes (based on the slot time of Ethernet), which yields a frame that consists of 72 bytes (see Table 1) plus a 12-byte inter-frame gap, for a ...
