How do you "List Physical Adapter Ports and Speed. 100Gb Ports."?

I've tried:
<code>lshwres -m FR24 -r sriov --rsubtype physport --level eth</code>
and
<code>lshwres -m FR24 -r sriov --rsubtype physport --level ethc</code>

And on the systems where we have 100GB SRIOV adapters, I get:
<code>no results were found.</code>
I'm still looking but I'm sure someone has the answer.

Thanks.

Hi Charin,
Good spot, probably a typo, it is three and I've edited the post.
Thanks.

Hi there,
I confused the explained of example 2 and 3.

Example 2

In this lssrad output, AIX has been told that the LPAR has been allocated CPU and memory from four different Chips in a single Node.
Q: Why is from four?

But in example 3 output.
- CPU from three different Chips in two Nodes, i agreed and i think it correct.
- memory from five different Chips in 3 nodes.
If you compare example 2 and 3 seems the explained for example 2 may be wrong.
Please let me if am i mistake.

Regards,
Charin Kumjudpai.

Use following : \&quot; \&quot; within virtual_scwitch_mappings
migrlpar -o v -m Server1 -t Server1 -p LPAR11 --ip 1.2.3.4 -u hscroot -i 'dest_lpar_id=5,&quot;virtual_scsi_mappings=1/vio1//50,2/vion2//51&quot;,
&quot;virtual_fc_mappings=3/vion1//52,4/vio1//53,5/vio2//54,6/vio2//55&quot;, &quot;vswitch_mappings=\&quot;123/ETHERNET0/Switch1,246/ETHERNET0/Switch2,345/ETHERNET0/Switch2\&quot;&quot;, shared_proc_pool_name=pool,source_msp_name=vioa,&gt;source_msp_ipaddr=1.2.3.8,dest_msp_name=vio2,dest_msp_ipaddr=1.2.3.9'

If you want to do all 4 sets:

/usr/bin/ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key -N ''

/usr/bin/ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key -N ''

/usr/bin/ssh-keygen -t ecdsa -f /etc/ssh/ssh_host_ecdsa_key -N ''

/usr/bin/ssh-keygen -t ed25519 -f /etc/ssh/ssh_host_ed25519_key -N ''

Thanks Bernhar,
I've updated the max_min description. It should be:
Attempt the maximum mode. If the maximum values cannot be allocated, then fall back to minimum mode.

Still wrong. The running adapter settings of max_min an max are identical therefore the explanation of max_min is wrong.

I use this one since the perl part not worked for me:

Example:

tcpdump -c 100 -e -i en66 'ether[12:2] = 0x8100' -w vlantest.pcap && tcpdump -v -n -e -r vlantest.pcap | awk -F "vlan" '{ print $2 }' | awk -F "," '{ print $1 }' | sort -nr | uniq -c

The tcpdump command is actually looking at the VLANs that are being bridged to the VIOS from the switch.
This can be useful when trying to diagnose VLAN related issues and you need to confirm the switch is actually sending the VLANs to the VIOS.

Whereas, the entstat command is only showing you what you have configured on the VIOS, not what the switch is sending.

Thanks and regards, Steve.

There is also a possibility to see the active VLANs on the VIOS based on entstat command.
entstat command is very helpful for any network configuration.
As an example, ent7 is one SEA :
# lsdev -Cc adapter | grep -i ent7
ent7 Available Shared Ethernet Adapter
# entstat -d ent7 | grep -i vlan
VLAN Ids :
Packets filtered(VlanId): 0
Packets filtered(VlanId): 0
Number of Receive VLAN Mismatch Errors: 0
VLAN ACL Status: Disabled
Invalid VLAN ID Packets: 0
Port VLAN ID: 998
VLAN Tag IDs: 125 18 328 418 760
Management VLAN: Disabled

Update on the tcpdump command.

Some switches do not return much data with the vlan and ether dst 01:00:0c:cc:cc:cd settings. I have found the following tcpdump command to be more reliable.

# tcpdump -i en26 -xx ether multicast

Hi Chris,
Good spot, I fixed that.
There is no difference I can see between min and max_min setting.

In your explanation of min, max, & max_min the last 2 are exactly the same.

Should it be:
min = the minimum values are used
max = the maximum values are used
max_min = the maximum AND minimum values are used

Thanks for clarification.

We are using 16Gb direct attached (direct connection onl support 16Gb). I think it is OK with 8Gb connection from fabric.

AIX7.1 TL3 SP 4

Hi,
VIOS is 2.2.5.10 connected to a SAN switch.
Port Speed (supported): 16 GBIT
Port Speed (running): 8 GBIT
Port FC ID: 0x??????
Port Type: Fabric
Attention Type: Link Up
Topology: Point to Point or Fabric

We are using the same EN0B card direct connect to SAN. But failed to connect to. I thought you are using the fabric to 16b FC SAN. Could you share the AIX and SAN OS Model?

Thanks

I used the smitty F6 option to work out the command line.

Big thanks. Did you determine the _-s pseudo -t ibm_ech_ via odm ?
