Switch-gpon-profile#no gpon-profile entry 1 port-protected

Step02: Apply the profile on the ONU

Switch_config# interface GPON0/2:4

Switch_config_gpon0/2:4# gpon onu flow-mapping-profile test

NB: If it is in different PON port need to use "no switchport protected" command and if it is in same PON port need to use "switchport reflect-bridge" command

This solution is applicable for only few models ONU with special firmware. That's why please contact with BDCOM team for this solution

47. How to configure port mirror in Switch/OLT

Switch#config

Switch_config#mirror session 1 destination interface g0/1

Switch_config#mirror session 1 source interface g0/2 both

NB: Here source port is the testing port and destination port is the packet capturing port (where the laptop is connected with Wireshark)

48. How to reset Switch/OLT if you forget the password

Please follow the steps -

1. Connect the console cable to the Switch/OLT with BDCOM console cable which is provided with the Switch/OLT

2. Reboot the Switch/OLT by power off/on

3. When Switch/OLT is rebooting just press "CTRL + P"

4. You will be able to see monitor# mode in the screen

5. Please use the command "show configuration". You will be able to see the password in clear text if the password was not encrypted

6. If you want to reset (factory default) the Switch/OLT use the command "delete startup-configuration"

7. Reboot the Switch/OLT and you will be able to access with default mode. username and password will be admin/admin.

8. Your all configuration will be lost and you need to configure your Switch/OLT again

49. How to configure ACL (Access Control List) in BDCOM Switch/OLT

A. Objective: tcp port number 22 (SSH) and tcp port number 161 (SNMP) will be allowed on physical port gig0/1 and all other tcp ports (like telnet, ftp etc.) will be blocked

Step01: Make a access-list named test

Swith#config

Switch_config#ip access-list extended test

Switch_config_ext#permit tcp any any eq 22

Switch_config_ext#permit tcp any any eq 161

Switch_config_ext# deny ip any any

Step02: Apply the access-group on the interface

Switch_config#

Switch_config#interface gigaEthernet 0/1

Switch_config_g0/1#ip access-group test

B. Objective: Only from 192.168.100.1 to 192.168.100.254 IPs are allowed to browse the switch in http port at 80. Other all IP will be denied

Swith#config

Switch_config#ip access-list standard test

Switch_config_std#permit 192.168.100.0 255.255.255.0

Switch_config_std#exit

Switch_config#ip http access-list test

50. How to configure VOICE VLAN

Swith#config

Switch_config#vlan 500,400

Swith#config

Switch_config#interface GigaEthernet0/1

Switch_config_g0/1#description IP-Phone

Switch_config_g0/1#switchport trunk vlan-allowed 500,400

Switch_config_g0/1#switchport trunk vlan-untagged 500, 400

Switch_config_g0/1#switchport pvid 500

Switch_config_g0/1#switchport mode trunk

Switch_config_g0/1#switchport voice-vlan mode mac-address

Switch_config_g0/1#switchport voice-vlan 400

Switch_config#voice-vlan mac-address 000b.82fe.932e mask ffff.ffff.ff00

NB: Here, Voice VLAN is 400 and MAC address 000b.82fe.932e is for IP phone.

We may add a specific single MAC address or vendor based MAC address. First 6 degit of vedor MAC and rest of 6 degits will be zeto. For example if Grandstream vendor's MAC addrss first 6 digit is 00:0b:82 then we may add the below command

Switch_config#voice-vlan mac-address 000b.8200.0000 mask ffff.ff00.0000

It's meaning all Grandstream's IP phone will be connected and vocie VLAN will be working perfectly.

54. How to configure STP/RSTP in OLT PON port or in the ONU?

STP (Spanning Tree Protocol) is a layer 2 network protocol that helps prevent loops in Ethernet networks by blocking redundant paths. Typically, STP operates at the data link layer (Layer 2) of the OSI model and is used in Ethernet networks.

In the context of PON (Passive Optical Network) technology, such as in OLT (Optical Line Terminal), the PON port itself doesn't pass STP frames. PON technology operates at the physical layer and is point-to-multipoint, meaning that it's a one-to-many communication model. Each Optical Network Unit (ONU) communicates directly with the OLT over the PON, and there is no need for STP to handle redundant paths which we can see in a traditional Ethernet network.

In a PON environment, STP is typically not necessary because the topology is inherently different from a traditional Ethernet network. The design of PON networks eliminates the need for STP by avoiding loops in the physical topology.

55. Why packet discards in the switch port?

Congestion: If the network is congested and the buffers on the switch are full, the switch will start dropping packets. This can happen during traffic bursts or if the switch is not able to handle the incoming traffic volume.
Errors on the Line: Physical issues such as faulty cables, connectors, or ports can cause errors that lead to discarded packets. CRC (Cyclic Redundancy Check) errors, for instance, occur when there’s data corruption, and the switch discards the corrupted packets.
Port Misconfiguration: Mismatches in configurations like speed, duplex settings, or VLAN assignments between the switch port and the connected device can lead to packet loss. For example, if one side is set to full duplex and the other to half duplex, collisions may occur, leading to discards.
Access Control Lists (ACLs): If there are ACLs or security policies applied to a port that filter certain types of traffic, the switch may drop packets that do not meet the allowed criteria.
Buffer Overflow: A switch port has limited buffer memory. When the buffer overflows due to excessive traffic, the switch will discard additional incoming packets until space frees up.
QoS (Quality of Service): If QoS policies are in place, packets that exceed the allocated bandwidth or priority limits might be discarded to maintain the integrity of prioritized traffic.
Broadcast Storms or Loops: A misconfigured network with loops or excessive broadcast traffic can overwhelm a switch, causing it to discard packets to protect its own resources.

56. How to configure RSPAN?

Remote Switch:

Swith#config

Switch_config#mirror session 1 destination interface g0/1 portbased rspan 10

Switch_config#mirror session 1 source interface g0/2 both

Switch_config#interface GigaEthernet0/1

Switch_config_g0/1#switchport mode trunk

Switch_config_g0/1#switchport trunk vlan-allowed 10

Office Switch:

Swith#config

Switch_config#mirror session 1 destination interface g0/2 portbased rspan 10

Switch_config#mirror session 1 source interface g0/1 both

Switch_config#interface GigaEthernet0/1

Switch_config_g0/1#switchport mode trunk

Switch_config_g0/1#switchport trunk vlan-allowed 10

Switch_config#interface GigaEthernet0/2

Switch_config_g0/2#switchport mode trunk

Switch_config_g0/2#switchport trunk vlan-allowed 10

NB: We have to create a VLAN and pass through that VLAN in every switch. Here we created VLAN 10
