SYROTECH OLT initial configuration

Today we are going to configure some initial configurations in Syrotech OLT and make it reachable to BSNL NIB.

Connect the OLT to your PC's Ethernet port and put the OLT default IP 192.168.8.100 in Browser.

You can write the Name / installed location of the OLT. you can also check the software version of the OLT and also uptime.

For security reasons kindly change the default password for the OLT.

Disable the telnet access for OLT as telnet is not safe protocol instead you can use SSH.

Now create 119 VLAN in OLT. BSNL is using VLAN 119 as Management VLAN for TIP OLTs.

Apply IP to VLAN 119.

Add static route

Now pass this VLAN to Uplink port to which you have attached BSNL Transmission system.

You can check the connectivity by pinging the BSNL provided gateway.

Finally save the configuration so that if OLT reboots due to power issue it comes up with same configuration as of before reboot.
