3. CONFIGURATION
3.6 ERS 1600 C ONFIGURATION E XAMPLE
The following configuration example demonstrates how to configure a centralized Nortel Ethernet Routing Switch 1600 to support a multiple subnet environment where the Microsoft Network Load Balancing cluster of servers and clients are connected to a subtended Layer 2 switches and are placed in separate IP subnets (VLANs).
Figure 3.6 – ERS 1612G Example Topology
3.6.1 ERS 1612G – Configuration
For the first step we will configure an Ethernet Routing Switch 1600 as follows:
1. Create VLAN 2 to support clients (VLAN 1 is enabled by default) 2. Enable 802.1Q tagging on ports 1 – 4
3. Assign ports 1 – 2 to VLAN 1 4. Assign port 3 – 4 to VLAN 2
5. Assign a IP address of 192.168.1.1/24 to VLAN 1 6. Assign a IP address of 192.168.2.1/24 to VLAN 2
7. Force speed and duplex on ports 3 – 4 to 1000Mbps FDX to support the ES 470-24T 8. Create a Multi-Link Trunk with ports 1 – 2 to connect the ERS 5510-24T server switch 9. Create a Multi-Link Trunk with ports 3 – 4 to connect the ES 470-24T client switch 10. Create a static ARP entry to support NLB multicast mode
______________________________________________________________________________________________________
Connect to the Ethernet Routing Switch 1600 and log into the CLI with the username “rwa” and the password “rwa”.
1. Create port based VLAN with a id 2 and name it VLAN2:
• PP1612G# create vlan VLAN2 vid 2 type port
2. Remove ports 3 – 24 from VLAN 1:
PP1612G# config vlan default delete 3-24
3. Add ports 1 – 2 to VLAN 1 and enable 802.1Q tagging:
• PP1612G# config vlan default add tagged 1-2
4. Add ports 3 – 4 to VLAN 2 and enable 802.1Q tagging:
• PP1612G# config vlan VLAN2 add tagged 3-4
5. Verify VLAN configuration:
______________________________________________________________________________________________________
6. Change the IP address for VLAN 1 to 192.168.1.1 and set the subnet mask to 255.255.255.0:
• PP1612G# config ipif System ipaddress 192.168.1.1/24
7. Create a IP Interface named VLAN 2_IF, set the IP address to 192.168.2.1 and the subnet mask to 255.255.255.0 and tie it to the VLAN named VLAN2:
• PP1612G# create ipif VLAN2_IF 192.168.2.1/24 VLAN2
8. Verify IP Interface configuration:
• PP1612G# show ipif the ports to 1000Mbps Full Duplex:
• PP1612G# config ports 3-4 speed 1000_full
______________________________________________________________________________________________________
10. Verify Ports 3 – 4 speed and duplex settings:
• PP1612G# show ports 3-4
11. Create Multi-Link Trunking group 1 and add ports 1 - 2:
• PP1612G# create link_aggregation group_id 1
• PP1612G# config link_aggregation group_id 1 master_port 1 ports 1-2
• PP1612G# config link_aggregation group_id 1 state enabled
12. Create Multi-Link Trunking group 2 and add ports 3 - 4:
• PP1612G# create link_aggregation group_id 2
• PP1612G# config link_aggregation group_id 2 master_port 3 ports 3-4
• PP1612G# config link_aggregation group_id 2 state enabled
13. Verify Multi-Link Trunking configuration:
______________________________________________________________________________________________________
14. In this instance we’re implementing Network Load Balancing with flood suppression so no additional configuration is required. However if you are implementing Network Load Balancing in multicast mode with no flood suppression, a static ARP entry needs to be created on the ERS 1600 so that the clients will be able to communicate with the clusters virtual IP address:
• PP1612G# create arpentry 192.168.1.50 03-bf-c0-a8-d2-32
15. Verify static ARP entry:
• PP1612G# show arpentry
ARP Aging Time : 20
ARP Req Rate Limit : Disabled
