Inter vlan routing doesn't work as expected on 2930M-48G

Hello everybody ,

it is a really simple test, i would routing between two Vlan's but i really don't know why doesn't work.

i have two clients : client 1 : 192.168.152.101 , 255.255.255.0 , GW : 192.168.152.1   ---> untagged to vlan 152

                                 Client 2 : 192.168.150.102 255.255.255.0 GW: 192.168.150.1    ---> untagged to vlan 150

Problem: NO routing between Vlan's 

Can you help me please ?   it's really important for me .   Thank you so much .

Re: Inter vlan routing doesn't work as expected on 2930M-48G

Hello! given the configuration posted say you have Host A (192.168.150.2/24 DG 192.168.150.1 = VLAN 150 SVI address) connected on Port 21 (Untagged member of VLAN 150) and Host B (192.168.152.2/24 DG 192.168.152.1 = VLAN 152 SVI address) connected on Port 23 (Untagged member of VLAN 152)...then, once IP Routing is enabled on the Switch, ICMP Ping tests between those hosts must work...provided that no OS Firewall/Antivirus jumps in to block that type of traffic/destination/source...and no Host's custom route to peer Host is conflicting with your tests.

Check: Ping to respective SVI Address, Ping to peer VLAN's SVI Address and then Ping to destination Host. Repeat on other Host.

Re: Inter vlan routing doesn't work as expected on 2930M-48G

thank you for your response .

Yes everything seems to be right and it should work , firewall and antivirus are disabled. 

the problem is i have no ROUTING. Host's are in their own Vlan's they have ping only to their own SVI address and host's that they are in same vlan.

Really confused . unfortunatly we must to run a project and have no time .

Very strange. Are you able to post (sanitized) outputs of show ip and show ip routing commands?

Those portions of VLAN table and Routing Table look good:

Internet (IP) Service

IP Routing : Enabled

Default TTL   : 64
Arp Age       : 20
Domain Suffix : 
DNS server    : 192.168.34.254

					 |                                            Proxy ARP
VLAN				 | IP Config  IP Address      Subnet Mask     Std Local
-------------------- + ---------- --------------- --------------- ----------
Backup DO			 | Manual     192.168.34.61   255.255.255.0    No   No
vlan-150			 | Manual     192.168.150.1   255.255.255.0    No   No
vlan-152			 | Manual     192.168.152.1   255.255.255.0    No   No

Destination 		Gateway			VLAN	Type 		Sub-Type	Metric		Dist.
------------------	--------------- ----	---------	----------	----------	-----
127.0.0.0/8			reject					static					0			0
127.0.0.1/32		lo0						connected				1			0
192.168.34.0/24		Backup DO		1		connected				1			0
192.168.150.0/24	vlan-150		150		connected				1			0
192.168.152.0/24	vlan-152		152		connected				1			0

Does show logging reports any warning/error? do you have ACL in place preventing routing between such VLANs? Have you tried to disable/enable the ip routing? What is the running software version?

no, not yet. i only want at the first have a routing between Vlan's and then ather things . I've also updated the software .

Re: Inter vlan routing doesn't work as expected on 2930M-48G

OK. I suggest you to start with updating your Aruba 2930M to latest WC.16.10.0002 of WC.16.10 software branch instead of staying on WC.16.07 software branch.

I'm pretty much sure there could be something weird on your hosts or on the switch (write memory and then reboot, then recheck status of VLAN, IP and IP Routing).
