Can some one help me solve my problem.
this is network topology:
Some PCs are connected to CRS ports.
no need for VLAN all network connected devices are in the same vlan.
I’ve connected CRS and CSS without configuring CRS device. Only default configuration and IP address change.
All work well; but after 3 or 4 hours any network can access to internet and I can not connect to any switch configuration interface.
but all connected device reply correctly to ping command (ping works).
*) fixed CRS317: make 10G links more stable;
*) fixed “Allow From VLAN” on untagged packets with correct default vlan id;
*) LACP: fixed unstable aggregate link problem when partner had short retransmit timer;
*) CSS326 & CRS317: made 1Gb fiber SFP module work with auto negotiation;
*) CSS106: do not VLAN tag RSTP packets;
I tested the new release but it did not solve the problem.
pleased find below network topology.
CRS configuration
CSS configuration Bellow
This is the problem:
When I connect fiber to Mikrotik switches and make a bridge with existing dlink switches all PC connected to dlink switches everything work fine. But when I connect PC to switch 1 and switch 2 network drops. pings respond correctly but no application is working: internet access, exchange, accounting, etc. And I can not access to switches management interface.
