How to check the ethernet status for vlan and lhea adapter in client servers?

Hi Techies,

I have a doubt.

Code:

ent0    Available       Logical Host Ethernet Port (lp-hea)
ent1    Available       Logical Host Ethernet Port (lp-hea)
ent2    Available       Logical Host Ethernet Port (lp-hea)
ent3    Available       Logical Host Ethernet Port (lp-hea)
ent4    Available 05-20 Gigabit Ethernet-SX PCI-X Adapter (14106703)
ent5    Available 05-21 Gigabit Ethernet-SX PCI-X Adapter (14106703)
ent6    Available       EtherChannel / IEEE 802.3ad Link Aggregation
ent7    Available       VLAN
ent8    Available       VLAN
fcs0    Available 03-00 PCI Express 4Gb FC Adapter (77103224)
fcs1    Available 03-01 PCI Express 4Gb FC Adapter (77103224)
fcs2    Available 02-00 4Gb PCIe FC Blade Expansion Card (7710322577106501)
fcs3    Available 02-01 4Gb PCIe FC Blade Expansion Card (7710322577106501)
lhea0   Available       Logical Host Ethernet Adapter (l-hea)
lhea1   Available       Logical Host Ethernet Adapter (l-hea)
sissas0 Available 00-08 PCI-X266 Planar 3Gb SAS Adapter
usbhc0  Available 01-08 USB Host Controller (33103500)
usbhc1  Available 01-09 USB Host Controller (33103500)
usbhc2  Available 01-0a USB Enhanced Host Controller (3310e000)
vsa0    Available       LPAR Virtual Serial Adapter

In this server , I can check the link status for etherchannel like :

Code:

 entstat -d ent6 | grep -i link
Device Type: IEEE 802.3ad Link Aggregation
Statistics for every adapter in the IEEE 802.3ad Link Aggregation:
IEEE 802.3ad Link Aggregation Statistics:
Logical Port Link State: Up
Physical Port Link State: Up
Link Status: Up

Similarly is there any way to check the link status of lhea and vlan adapters ??

Thanks & Regards,
Jayadeava

Also need to add that, I do not have access to the vio server. Hence wanted to know if there is any way to check the link status from the client machine itself.

Thanks in Advance.

I have 2 VIO servers and a network connection to each of them in an etherchannel so running entstat against the individually adapters doesn't work.

Code:

host:/:$ lsdev | grep ^ent
ent0         Available       Virtual I/O Ethernet Adapter (l-lan)
ent1         Available       Virtual I/O Ethernet Adapter (l-lan)
ent2         Available       EtherChannel / IEEE 802.3ad Link Aggregation
host:/:$ entstat -d ent0

entstat: 0909-003 Unable to connect to device ent0, errno = 19
host:/:$

I do see this info in the entstat output for the etherchannel. Since virtual adapters don't really have "links", I think the comparative is "LAN State":

Code:

host:/:# entstat -d ent2
Number of adapters: 2
Active channel: primary channel
Operating mode: Network interface backup mode
...
ETHERNET STATISTICS (ent0) :
Device Type: Virtual I/O Ethernet Adapter (l-lan)
...
LAN State: Operational
...
ETHERNET STATISTICS (ent1) :
Device Type: Virtual I/O Ethernet Adapter (l-lan)
...
LAN State: Operational

The SEA is configured on the VIO server and without access to the VIO server, I don't think you have any way to see if there is one. I don't think the LPAR itself (not VIO server) would even know if it exists.

The LPAR's ethernet adapter is created on a VLAN matching what is on the VIO server's, but I don't know of any way to see the VLAN number from the LPAR. If you have access to the HMC, you can see it there.

you cannot check physical SEA interface from the LPAR. LPAR itself cannot see if the SEA (VIOS) interface does (not) have a link.
Only the way is using ping test to the default gateway ... it something what even ehterchannel relies on client LPARs
