Solaris NIC speed and duplex settings

In solaris 10, we have this very useful command to check the state of the NIC..

# dladm   show-dev 
bge0            link: up        speed: 1000  Mbps       duplex: full 
bge1            link: unknown   speed: 0     Mbps       duplex: unknown 
e1000g0         link: up        speed: 1000  Mbps       duplex: full 
e1000g1         link: unknown   speed: 0     Mbps       duplex: half 
e1000g2         link: up        speed: 1000  Mbps       duplex: full 
e1000g3         link: up        speed: 100   Mbps       duplex: full 
bge2            link: up        speed: 1000  Mbps       duplex: full 
bge3            link: up        speed: 1000  Mbps       duplex: full 
e1000g4         link: up        speed: 1000  Mbps       duplex: full 
e1000g5         link: unknown   speed: 0     Mbps       duplex: half 

# dladm show-link 
bge0            type: non-vlan  mtu: 1500       device: bge0 
bge1            type: non-vlan  mtu: 1500       device: bge1 
e1000g0         type: non-vlan  mtu: 1500       device: e1000g0 
e1000g1         type: non-vlan  mtu: 1500       device: e1000g1 
e1000g2         type: non-vlan  mtu: 1500       device: e1000g2 
e1000g3         type: non-vlan  mtu: 1500       device: e1000g3 
bge2            type: non-vlan  mtu: 1500       device: bge2 
bge3            type: non-vlan  mtu: 1500       device: bge3 
e1000g4         type: non-vlan  mtu: 1500       device: e1000g4 
e1000g5         type: non-vlan  mtu: 1500       device: e1000g5
