8.2.1. 7-port Ethernet Switch BCM53115M
The BCM53115 is a 7-port Ethernet switch with five tri-speed MACs and two GMACs
respectively. On the board, five tri-speed MAC ports (P0 ~ P4) and one GMAC port are
used. Figure 8-9 shows such connections and the port mapping can be found in Table
8-4. The features of the switch are summarized in the following:
• One
GMII/RGMII/MII/RvMII/TMII/RvTMII Interface for an inband management port
(IMP) for connection to a CPU/management entity without PHY.
•
One GMII/RGMII/MII/RvMII or SGMII/SerDes Interface for WAN management port
•
Five-port 10/100/1000 transceiver for TX
•
Dual IPM port support, WAN Interface(Port5) to be management port-capable
• IEEE802.1p
• Port-based
VLAN
•
IEEE802.1Q-based VLAN with 4K entries
•
MAC-based trunking with automatic link failover
•
Port-based rate control
• Port
mirroring
•
BroadSync HD for IEEE802.1AS support
•
DoS stack prevention
•
IGMP snooping, MLD snooping support
•
Spanning tree support(multiple spanning trees, up to eight)
•
CableChecker with unmanaged mode support
• Double
tagging/QinQ
•
Egress VID remarking
•
IEEE802,3az EEE(Energy Efficient Ethernet)
• IEEE802.1AS
support
•
4K entry MAC address table with automatic learning and aging.
•
128KB packet buffer(1KB = 1024bytes)
•
128 multicast group support
•
Jumbo frame support up to 9720 byte
The port LED configurations are:
• Port0 : LED[15]: SPEED 1G, LED[18]: LINK/ACT
• Port1 : LED[14]: LINK/ACT
• Port2 : LED[10]: LINK/ACT
• Port3 : LED[6]: LINK/ACT
• PHY Register setting for the LED control stays with a default value.
The base switch requires three power rails of 3.3V, 2.5V and 1.2V, which requires
power sequencing in the following order: 3.3V->2.5V->1.2V.
