Brocade SAN Switch Cheatsheet

System Management

Connection and Basics

Default Login: admin / password
Check Switch Status: switchshow (Provides status, domain ID, and port states)
Check Firmware Version: version
Reboot Switch: reboot

Configuration Management

# View all configuration settings
configshow

# Back up configuration to an external server
configupload

# Restore configuration from a server
configdownload

# Set the switch name
switchname "Brocade_SAN_01"

Interface Management

Port Status and Control

# Enable a port
portenable <port_number>

# Disable a port
portdisable <port_number>

# Detailed port statistics and errors
portstatsshow <port_number>

# Clear port statistics
portstatsclear <port_number>

To see which devices (WWNs) are physically connected to the ports:

# Show all logged-in devices and their WWNs
flogishow
# OR
portloginshow <port_number>

SAN Zoning (Brocade Logic)

Brocade uses a three-step logic: Aliases -> Zones -> Configuration (CFG).

1. Create Aliases

Aliases make WWNs human-readable (e.g., naming a WWN "Server_HBAs").

# Create an alias
alicreate "Alias_Name", "WWN"
# Example
alicreate "SRV_PROD_01", "21:00:00:24:ff:50:05:04"

# Add members to an existing alias
aliadd "Alias_Name", "WWN"

2. Create Zones

Zones define which aliases can talk to each other (usually 1 Initiator + 1 Target).

# Create a zone
zonecreate "Zone_Name", "Alias1; Alias2"
# Example
zonecreate "Zone_SRV01_Storage", "SRV_PROD_01; Storage_Port_A"

3. Create and Activate Configuration

The Zone Configuration (CFG) is a container for all the zones you want active.

# Create a new configuration and add a zone
cfgcreate "CFG_Name", "Zone_Name"

# Add a zone to an existing configuration
cfgadd "CFG_Name", "Zone_Name"

# Save the changes to non-volatile memory
cfgsave

# Enable the configuration (This makes the zoning live)
cfgenable "CFG_Name"

Maintenance and Troubleshooting

Zoning Verification

# View the defined (offline) configuration
cfgshow

# View the currently active zoning in the fabric
cfgactiveshow

# Find a specific WWN in the zone database
zoneshow | grep -i "21:00:..."

Fabric Troubleshooting

Check Fabric Membership: fabricshow (Shows all switches in the fabric)
Monitor Environment: chassisshow (Status of fans, power supplies, and temperature)
SFP Diagnostics: sfpshow <port_number> (Shows light levels and SFP health)

General Principles

Persistence: Always run cfgsave after your modifications; otherwise, changes may be lost if the switch reboots.
Case Sensitivity: Command names and Aliases/Zones are often case-sensitive in FOS.
The "no" equivalent: In Brocade, use delete or remove commands (e.g., alidelete, zonedelete, cfgdelete).
