Trouble with bidirectional ping

jesus_mazon — Thu, 09 Apr 2015 03:04:00 GMT

Hello everyone,

I have a problem with my switch configuration, the topology is the next:

In the ports 1-4 are my servers of videoconferencing and the ports 45-46 are the gateways to two junipers.

In the ports 25-28 are two Cisco VCS’s and a Dell Server, ports 47-48 are the gateways to the local core.

The configuration is the following:

show conf

#

# Module devmgr configuration.

#

configure snmp sysName "Infotec"

configure sys-recovery-level switch reset

#

# Module vlan configuration.

#

configure vlan default delete ports all

configure vr VR-Default delete ports 1-64

configure vr VR-Default add ports 1-64

configure vlan default delete ports 1-4, 25-28, 30, 45-48

configure vlan Acano tag 61

create vlan "Local"

configure vlan Local tag 421

enable sharing 47 grouping 47-48 algorithm address-based L2 lacp

configure vlan Acano add ports 1-4, 45-46 untagged

configure vlan Default add ports 5-24, 29, 31-44, 49-64 untagged

configure vlan Local add ports 25-28, 30, 47 untagged

configure vlan Mgmt ipaddress 192.168.127.5 255.255.255.0

#

My question is that my switch can reach everyone and vice versa, but the servers of videoconferencing can’t reach no one of the switch. I already try with LLDP, LACP, even EDP, and no luck, is there some other protocol to try or what can I do? I really appreciate all your help.

Hi,

you have 2 vlans: Acano and Local, but ip address and ipforwaring are set only for vlan Local.
Is it correct config ? Do you have routing to those vlans somewhere else ? ( local core or gateways )

Another thing that I've noticed is that your network management vlan is in the same network as vlan "local" - I don't know what can of worms that opens. (And what Jarek said, of course  )
