Brocade VDX Aggregated Links

Aggregated Links between two Brocade VDX 6720 switches:

Connect the two Brocade VDX switches using the 10Gb ports.
Example:
VDX Switch1 port1 to VDX Switch2 port1
VDX Switch1 port2 to VDX Switch2 port2
In the above example, A 20Gb linked between the two VDX switches. You can have up to 80Gb of aggregated bandwidth if you connect ports 1 through 8 on each VDX.

To create ECMP paths between two VDX’s, add more aggregated bandwidth between ports 13 to 24.
Example:
VDX Switch1 port13 to VDX Switch2 port13
VDX Switch1 port14 to VDX Switch2 port14
In both examples above, you will have two 20Gb paths between both Brocade VDX’s.

Brocade VDX iSCSI LLDP Configuration

Brocade VDX6720 LLDP and TLV Configuration

Enabling LLDP globally (by default, LLDP is enable globally):

1. Enter configure to access global configuration mode:
VDX6720# configure

2. Enter LLDP configuration mode:
VDX6720(config)# protocol lldp
Note: To Disable LLDP globally:”no protocol lldp”

3. You’re in LLP configuration mode designated by (conf-lldp)# prompt.
Type ? to see what command options that applies globally to all interfaces
VDX6720(conf-lldp)# ?

Examples, To advertise LLDP DCBX related TLVs:
VDX6720(conf-lldp)# advertise dcbx-fcoe-app-tlv
VDX6720(conf-lldp)# advertise dcbx-fcoe-logical-link-tlv
VDX6720(conf-lldp)# advertise dcbx-tlv

Configuring iSCSI DCBX LLDP

1. Enter configuration mode terminal:
VDX6720# configure

Steps 2 to 4 are Global configurations
######################################
2. Enter LLDP configuration mode:
VDX6720(config)# protocol lldp

3. Configuring iSCSI priority:
VDX6720(conf-lldp)# lldp iscsi-priority 4

4. Advertise the TLV:
VDX6720(conf-lldp)# advertise dcbx-iscsi-app-tlv
######################################

5. Create a LLDP profile for iSCSI:
VDX6720(conf-lldp)# profile iscsi_config

6. Description of the Profile:
VDX6720(config-profile-iscsi_config)# description standard_iscsi_profile

7. Enable the transmitting and receiving of LLDP frames:
VDX6720(config-profile-iscsi_config)# mode tx

VDX6720(config-profile-iscsi_config)# mode tx

8. configure transmission frequency and hold time for receiving devices:
VDX6720(config-profile-iscsi_config)# hello 10

VDX6720(config-profile-iscsi_config)# multiplier 2

9. Advertise the iSCSI TLV
VDX6720(config-profile-iscsi_config)# advertise dcbx-iscsi-app-tlv

10. Exit to temimal mode:
VDX6720(config-profile-iscsi_config)# end

###########################################################

Configure the cee-map (if it hasn’t already been created).
Example:
VDX6720# configure
VDX6720(config)# cee-map default

VDX6720(config-cee-map-default)# priority-group-table 1 weight 30 pfc off

VDX6720(config-cee-map-default)# priority-group-table 2 weight 30 pfc off

VDX6720(config-cee-map-default)# priority-group-table 3 weight 40 pfc on

VDX6720(config-cee-map-default)# priority-table 2 2 2 1 3 2 2 15.0

VDX6720(config-cee-map-default)# end
###########################################################

11. Configuration the specific interface, example port 2:
VDX6720# configure
VDX6720(config)# interface TenGigabitEthernet 1/0/2

12. Apply the CEE Provisioning map:
VDX6720(conf-if-te-1/0/2)# cee default

13. Appply the LLDP profile created “iscsi_config”:
VDX6720(conf-if-te-1/0/2)# lldp profile iscsi_config

14. Set the iSCSI priority bits for the interface:
VDX6720(conf-if-te-1/0/2)# lldp iscsi-priority 4

Repeate 11 to 14 for other ports (interfaces).
