Portchannel question

[grapevine]

We have 3 Cisco IE-9320 in a stack. We have a Portchannel connecting to ESXI from switch 2 port 3 and switch 3 port 4

4 Po4(SU) - Gi2/0/3(P) Gi3/0/4(P).

Ports are in bundled.

GigabitEthernet2/0/3 media type is 10/100/1000BaseTX SFP

GigabitEthernet3/0/4  media type is 10/100/1000BaseTX 

ESXI nic teaming is configured as Route based on IP hash.

Ping to esxi is dropping intermittently

SW01#sh run int Po4
Building configuration...

Current configuration : 127 bytes
!
interface Port-channel4
switchport trunk allowed vlan 16,18
switchport mode trunk
end

SW01#sh run int Gi2/0/3
Building configuration...

Current configuration : 168 bytes
!
interface GigabitEthernet2/0/3
switchport trunk allowed vlan 16,18
switchport mode trunk
channel-group 4 mode on
end

SW01#sh run int Gi3/0/4
Building configuration...

Current configuration : 168 bytes
!
interface GigabitEthernet3/0/4
switchport trunk allowed vlan 16,18
switchport mode trunk
channel-group 4 mode on
end

arp is incomplete for esxi in firewalls. please advise how to fix it

Hello
If the ESXI teaming supports it change the PC both ends from a static to dynamic (LACP)

[grapevine]

ESXI's current license  doesn't support LACP

@grapevine hi, looks like configuration is ok. is there any specific ARP are you looking for?

do you have any test VM on esxi with IP address form VLAN16,18 to test? 

and , did you configured teaming at vswitch in esxi?

[grapevine]

It was working fine and stopped all of a sudden. I am not able to ping any vms inside the esxi. There are vms in vlan 16 and 18

[MHM Cisco World]

In SW do

Show vlan brief <<- share this

MHM

[grapevine]

[MHM Cisco World]

Show interface trunk 

Show switchport interface <PO> 

Show switchport interface <g2/0/3 & g3/0/4>

Share this please 

MHM

[Kasun Bandara]

@grapevine ok. so its sudden issue. was there any changes on server side or switch side? and as @MHM Cisco World mentioned, can you share the vlan information from switch, and #sh etherchannel sum, and check if there is any VLAN changes at VSwitch in esxi.

[grapevine]

No changes were made as far as I remember

Hello
On the cicso portchannel

int port 4
spanning-tree portfast trunk

[MHM Cisco World]

Show switchport interface 

Not show interface 

Let see if port member and PO run as trunk not as access interface 

MHM

[grapevine]

I dont see show switchport interface command listed

PVW-CSW01#show switch?
switch

I found out something now

Switch 3 in the stack has rebooted. We saw this in the past when switch reboots and adds in the stack the connected esxi and servers go offline, server guys did some changes in the esxi and it came back online

Switch 03

Switch uptime : 18 hours, 39 minutes
