Uplink Name
|
The uplink name is mandatory. It must be a string of up to 20 characters, including letters, digits, and underscores (_). It cannot start with an underscore.
|
Uplink Type
|
- Share Uplink: used by multiple Business VLANs whose VLAN Type is Normal Vlan or Trans Vlan at the same time.
- Normal Uplink: used by a Business VLAN whose VLAN Type is Normal Vlan or Domain Vlan.
- Cascade Uplink: used for cascading the switch modules of two or more chassis. This type can be selected only when Work Mode of the switch modules is set to Tradition and Work Relation is set to Stack.
NOTE: A cascade uplink is only used for cascading chassis. If a cascade link belongs to the same business VLAN as other uplink types, do not connect the cascade uplink to external switches; otherwise, network loops will occur.
|
Interface Type
|
- Eth-Trunk: allows multiple physical links to be bound as a logical link to increase bandwidth, implement load sharing, and improve system reliability. This is also referred to as Ethernet link aggregation.
- Smart Link: allows two ports to work in active/standby mode. Normally, one port is active, and the other is blocked and in the inactive state. When the active port is unavailable, the other port is activated for data transfer.
- Physical Link: indicates a common physical link.
The default value is Eth-Trunk.
|
Negotiation
|
- If Negotiation is Enabled, the port auto-negotiation configuration retains the default setting.
- If Negotiation is Disabled, you need to configure the uplink speed value based on the port type.
NOTE: - If the speeds at the uplink port and the connected port are different, the two ports cannot communicate with each other. You are advised to set Negotiation to Enabled.
- The Negotiation configuration only applies to GE ports, but does not apply to 10GE and 40GE ports.
|
Notes
|
Provides additional information. This parameter is optional but cannot contain any Chinese characters. The value can contain a maximum of 47 characters.
|
Smart Channel Configuration
|
Set Smart Channel Configuration when Work Mode is set to Smart Channel.
- Set Member Port Mode.
- Auto: The Link Aggregation Control Protocol (LACP) is used to negotiate with external switches to automatically add member ports to Trunk A or Trunk B.
- Manual: You need to manually specify the member ports to be added to Trunk A or Trunk B.
- Click Modify Member Port. The Please Select Physical Ports dialog box is displayed. In the Available Ports lists, select ports, and double-click or click Add to add the ports to Selected Ports in Auto mode or to TrunkA Ports and TrunkB Ports in Manual mode.
NOTE: You must select at least two ports. If Work Relation is set to Stack, the selected ports must be on switch modules in different slots. Table 2 describes the port formats.
- Set Least Active Link Number based on the actual situation.
Minimum number of active links: specifies the minimum active links in a link aggregation group.
|
Eth-Trunk Configuration
|
Set Eth-Trunk Configuration when Work Mode is set to Tradition and Interface Type is set to Eth-Trunk.
- Click Modify Ports. In Available Ports, double-click the port or select the port and click Add to add the port to the Selected Ports list.
NOTE: You must select at least two ports. If Work Relation is set to Stack, the selected ports must be on switch modules in different slots. Table 2 describes the port formats.
- Sets the mode to Manual or LACP based on the actual situation.
- Manual: The Eth-Trunk links work in manual load balancing mode.
- LACP: The Eth-Trunk links work in static LACP mode.
- LACP Timeout: specifies the maximum time allowed for receiving packets.
- Slow: The timeout period is 3 seconds.
- Fast: The timeout period is 90 seconds.
- Sets the number of active links.
- Minimum number of active links: specifies the minimum active links in a link aggregation group.
- Maximum number of active links: specifies the maximum active links in a link aggregation group, this parameter takes affect only when the mode is set to LACP.
|
Smart Link Configuration
|
Set Smart Link Configuration when Work Mode is set to Tradition and Interface Type is set to Smart Link.
- Click Modify Ports. In Available Master Ports, double-click the ports or select the ports and click Add to add the ports to the Selected Master Ports list.
NOTE: You must select at least one master port and one slave port. The number of selected master ports must be the same as the number of selected slave ports. If Work Relation is set to Stack, you are advised to select ports on switch modules in different slots. Table 2 describes the port formats.
- Create the Eth-Trunk port.
NOTE: - If the number of the master or slave ports is more than one, the Eth-Trunk port is created automatically.
- If the number of the master or slave ports is one, the Eth-Trunk port is not created by default.
- Manual: The Eth-Trunk links work in manual load balancing mode.
- LACP: The Eth-Trunk links work in static LACP mode.
- Least Active Link Number: specifies the minimum active links in a link aggregation group.
- Max Active Link Number: specifies the maximum active links in a link aggregation group, this parameter takes affect only when the mode is set to LACP.
- Set the Flush packet sending function.
- By default, this function is disabled.
- If Uplink Type is set to Normal Uplink, you do not need to set Flush Control VLAN ID.
- Flush Control VLAN ID: The value range is 2 to 4063.
- If the switch module type is CX311:
- Work Relation is set to Stack, the VLAN ID cannot be 1002 or 1003. VLANs 1002 and 1003 are used by FCoE data by default.
- Work Relation is set to Twin, the VLAN ID cannot be 1002. VLAN 1002 is used by FCoE data by default.

Physical Link Configuration
|
Set Physical Link Configuration when Work Mode is set to Tradition and Interface Type is set to Physical Link.
Select physical ports in the list. Table 2 describes the port formats.
