IronWare Software Release 07.2.02j for Brocade FastIron switches
Release Notes v 1.0 Page 18 of 79
VRRP show command output
In some of the VRRP show command outputs in the FastIron Configuration Guide, Hello-Interval and
Dead-Interval timers are displayed in seconds instead of milliseconds.
48-port 10/100/1000 Mbps Ethernet POE (SX-FI48GPP) interface module
limitations
The following configuration limitations apply to this module:
• Q-in-Q and SAV (VLAN stacking) are not supported on this module.
• For systems with this module and IPv4 or IPv6 interface modules or management modules with user
ports:
• GRE tunnels and IPv6 over IPv4 tunnels are not supported.
NOTE: If the SX-FI48GPP module is inadvertently inserted in a system that has IPv4 or IPv6
interface modules, or a management module with user ports, existing tunnels will be taken
down immediately. To recover, you must physically remove the module that caused the
mix-and-match condition, then disable and re-enable the tunnel interfaces.
• Legacy ports and 48 Gbps copper ports cannot be members of the same trunk.
• Virtual cable testing (CLI command phy cable-diag tdr) is not supported on the SX-FI48GPP module
in software release 07.2.02.
New limit for IPv4 system-max ip-cache
For FCX and FastIron X Series devices, the maximum value for system-max ip-cache (IPv4) is reduced
from 256000 to 32768. When you upgrade to release 07.2.02 and if your configuration has an ip-cache
value greater than 32768, it will be automatically reduced to 32768.
ACL Statistics on FGS, FLS, and FWS devices
The FGS, FLS, and FWS do not support the use of traffic policies for ACL statistics only (CLI command
traffic-policy <TPD name> count). However, these models do support the use of traffic policies for ACL
statistics together with rate limiting traffic policies. For more information, refer to “Enabling ACL
statistics with rate limiting traffic policies” in the FastIron Configuration Guide.
IGMP Snooping feature limitation on FESX, SuperX, and FSX devices
High CPU utilization will occur when IGMP Snooping and PIM/DVMRP routing are enabled
simultaneously on a FESX, SuperX, or FSX router. With IGMP Snooping and PIM/DVMRP Routing
enabled simultaneously on a given system, IP Multicast data packets received in the snooping VLAN(s)
will be forwarded to client ports via the hardware; however, copies of these packets will also be
received and dropped by the CPU.
Show interface brief command output
If a port name is longer than 8 characters, the port name will be truncated in the output of the show
interface brief command.
