Brocade(config)#sntp broadcast client
Brocade(config)#sntp broadcast server 1.1.1.1
To enable an SNTP client to listen to only one specific IPv6 NTP broadcast server, enter the following
commands.
Brocade(config)#sntp broadcast client
Brocade(config)#sntp broadcast server ipv6 2001:179:2:1::1
Syntax: sntp broadcast server [<ip-address> | ipv6 <ipv6-address>]
The sntp broadcast client command must be configured with the sntp broadcast server command to
allow for an SNTP client to listen to only one specific NTP server.
When both unicast and broadcast modes are enabled for an SNTP client, the priority by which the NTP
server is used to update the client’s clock is as follows.
• The last responsive unicast server.
• The broadcast server on any interface.
qd commands on FGS and FLS devices
Information on configurable descriptor and configurable buffer for qd commands for FGS and FLS
devices in the configuration guide is incorrect.
• The maximum configurable descriptors using the qd-descriptor command is 3999.
• The maximum configurable buffer using the qd-buffer command is 2904.
Flow control on SuperX devices
The FastIron Configuration Guide states that all FastIron devices support asymmetric flow control,
meaning they can receive PAUSE frames but cannot transmit them. This is true for FastIron devices with
the exception of SuperX devices; symmetric flow control is turned on by default on SuperX devices.
SSH key generation time
The authentication and encryption algorithms have changed to be more secure. The increased security
affects SSH key generation time. The new SSH key generation time ranges apply only to initial key
generation. Refer to the following table for initial SSH key generation time ranges.
