UAPs Uplink master slave port configure ZTE OLT

[boxads]

Today i will be discuss how to UAPs Uplink master slave port configure ZTE OLT

Prerequisites:

  • Make sure that the network device works normally.
  • Uplink ports work normally.
  • Log in to the ZXA10 C220 through HyperTerminal or Telnet.

Context:

ZXA10 C220 supports UAPS. When the working uplink port is faulty, the service is switched to the backup uplink port automatically.

To configure the UAPS, perform the following steps:

1. Use the configure terminal command to enter global configuration mode.
2. Use the uaps-group command to configure UAPS group.
3. Use the port command to configure main and backup ports of UAPS group.
4. Use the revertive enable command to enable UAPS auto-recovery function.
5. Use the swap command to swap UAPS master and slave ports by force.
6. Use the switch command to configure UAPS group properties.
7. Use the next-hop command to configure UAPS next hop IP address of link detection.
8. Use the retry-link-detect command to configure UAPS retry times of link detection.
9. Use the interval-link-detect command to configure UAPS interval of link detection.
10. Use the show uaps groupid command to query UAPS configuration.

Link Aggregation Configure ZTE GPON OLT

[boxads]

Today i will be discuss how to Link Aggregation Configure ZTE GPON OLT.

Prerequisites:

  • Make sure that the network device works normally.
  • Uplink ports work normally.
  • Log in to the ZXA10 C220 through HyperTerminal or Telnet.

Context:

LACP is a method to control the bundling of several physical ports together to form a single logical channel. LACP allows a network device to negotiate an automatic bundling of links by sending LACP packets to the peer (directly connected device that also implements LACP). The logical channel on the ZXA10 C220 is called smartgroup, which has the same VLAN properties as Ethernet port.

To configure the link aggregation, perform the following steps:

1. Use the configure terminal command to enter global configuration mode.
2. Use the interface smartgroup command to configure smartgroup.
3. Use the smartgroup load-balance command to configure load-balance mode.

Note: The ZXA10 C220 supports six types of load-balance:

  • Based on source IP address
  • Based on destination IP address
  • Based on source and destination IP addresses
  • Based on source MAC address
  • Based on destination MAC address
  • Based on source and destination MAC addresses

The default mode is based on source and destination MAC addresses.

4. Use the interface command to configure interface configuration mode.
5. Use the smartgroup mode command to configure smartgroup port and mode.

Note:

  • On: The port runs static trunk. Both end of the aggregated link should be set to the on mode.
  • Active: The port runs LACP in active negotiation mode.
  • Passive: The port runs LACP in passive negotiation mode.
  • It is recommended to set one end to active mode and the other end to passive, or set both ends to active.
  • The VLAN attribues of a member port should be consistent with that of the smartgroup. Otherwise, the port cannot be added to the smartgroup.

6. Use the show lacp internal command to query smartgroup configuration.

TACACS Configure in ZTE OLT

[boxads]

Today i will be discuss how to TACACS Configure in ZTE OLT.

Prerequisites:

  • Make sure that the network device works normally.
  • Log in to the ZXA10 C220 through HyperTerminal or Telnet.

Context:

TACACS+ is an AAA protocol. TACACS+ supports independent AAA functions, allowing different TACACS+ security servers to work as the authentication, authorization, and accounting servers.

To configure the TACACS+, perform the following steps:

1. Use the configure terminal command to enter global configuration mode.
2. Use the tacacs enable command to enable TACACS+ function.
3. Use the tacacs-server host command to configure TACACS+ server.
4. Use the tacacs-server key command to configure TACACS+ shared encryption key.
5. Use the tacacs-server packet command to configure TACACS+ packet size.
6. Use the tacacs-server timeout command to configure TACACS+ time-out period.
7. Use the aaa group-server tacacs+ command to configure TACACS+ AAA server group.
8. Use the server command to configure TACACS+ server IP address in the AAA server group.
9. Use the aaa accounting command to configure AAA accounting method.
10. Use the aaa authentication command to configure AAA authentication method.
11. Use the aaa authorization command to configure AAA authorization method.

Today i will be discuss how to RADIUS Configure in ZTE OLT.

Prerequisites:

  • Make sure that the network device works normally.
  • Log in to the ZXA10 C220 through HyperTerminal or Telnet.

Context:

RADIUS is a standard AAA protocol.
The ZXA10 C220 supports RADIUS authentication for Telnet user.

To configure the RADIUS, perform the following steps:

Step-1. Use the configure terminal command to enter global configuration mode.
Step-2. Use the radius authentication-group command to configure RADIUS authentication group.
Step-3. Use the server command to configure RADIUS server.
Step-4. Use the algorithm command to configure RADIUS algorithm.
Step-5. Use the timeout command to configure RADIUS time-out time.
Step-6. Use the deadtime command to configure RADIUS invalid time.
Step-7. Use the max-retries command to configure RADIUS maximum retry times.

Stack VLAN Configure in ZTE OLT

[boxads]

Today i will be discuss how to Stack VLAN Configure in ZTE OLT

Prerequisites:

  • Make sure that the network device works normally.
  • The ONU is registered.
  • Log in to the ZXA10 C220 through HyperTerminal or Telnet.

Context:

In VLAN stacking application, when the ZXA10 C220 receives an upstream untag packet on the GPON-ONU port, it adds both PVID and CPVID (CVLAN PVID) to the packet.

To configure the VLAN stacking, perform the following steps:

Step-1. Use the configure terminal command to enter global configuration mode.
Step-2. Use the interface command to enter the GPON-ONU configuration mode.
Step-3. Use the switchport default vlan command to configure port PVID.
Step-4. Use the switchport default cvlan command to configure port CPVID.

Configure VLAN Translate in ZTE OLT

[boxads]

Today i will be discuss how to Configure VLAN Translate in ZTE OLT.

Prerequisites:

  • Make sure that the network device works normally.
  • The ONU is registered.
  • Log in to the ZXA10 C220 through HyperTerminal or Telnet.

Context:

According to VLAN translate rules, when the ZXA10 C220 receives upstream tag packets on the GPON-ONU port, it modifies the user VLAN tags to CVLAN tags and adds SVLAN tags to the packet. When the packets arrive at the port on the opposite end, the packets are sent to the user according to the CVLAN tags after the SVLAN tags are removed.

To configure the VLAN translate, perform the following steps:

Step-1. Use the configure terminal command to enter global configuration mode.
Step-2. Use the interface command to enter the GPON-ONU configuration mode.
Step-3. Use the switchport mode command to configure port VLAN mode.
Step-4. Use the switchport translate command to configure VLAN translate rule.

Note:

  • In a VLAN, VLAN QinQ and VLAN translate can not be configured simultaneously.
  • User VLAN ID and SVLAN ID must be different.
