VES-1000 Series Ethernet Switch
Switch-Related Commands 24-3
Figure 24-2 Port Status Command
“0x” denotes a hexadecimal number. Let’s look at the bolded number (1003) in Figure 24-2 .
Bits of interest are described as follows. Four binary bits (a nibble) make up each hex digit1. The leftmost bit in
the first nibble denotes if the link is down or up. “0” means the link is up, “1” means the link is down.
Hex 1 0 0 3
Binary Equivalent Nibbles 0 001 0000 0000 01 11
The rightmost bit-pair in the last nibble show rate and duplex mode as described in the next table.
Table 24-2 Port Status Command
LAST HEX DIGIT RIGHTMOST NIBBLE BIT-PAIR RATE DUPLEX MODE
0 00 10Mbps Half Duplex
1 01 10Mbps Full Duplex
2 10 100Mbps Half Duplex
3 11 100Mbps Full Duplex
24.4 VLANs
Please refer to the section about VLANs for some background information on VLANs in general.
The factory default port-based VLAN settings for VES are summarized below (see also Figure 24-3) :
•
Port 0 (the CPU management port) forms a VLAN with all VDSL ports and can use the Ethernet port(s) as the
uplink.
•
The VDSL ports cannot talk to each other.
•
Each VDSL port forms a VLAN with each Ethernet port and vice versa.
