Hello Luis,
a packet size of 500B is well inside the typical Ethernet frame data size (64B to 1500B). That should just work.
Did you check the GTAC Knowledge article
How to enable inter-VLAN routing in EXOS? One important step is to
enable ipforwarding after configuring the IP addresses.
You might want to verify that auto-negotiation is working:
show ports configuration no-refreshSpeed and duplex settings of switch and hosts need to match. Auto-negotiation is usually working fine, thus you should verify that all switch ports and hosts use it.
If you want to use IP packets larger than 1500B, then you need to enable
Jumbo Frames on the switch, and configure an appropriate MTU on the IP interfaces:
enable jumbo-frame ports all configure ip-mtu
SIZE vlan
VLANNAME Best regards,
Erik
