ip vlan-flooding
Enable unicast data traffic flooding on VLAN member ports.
E-Series
Syntax
ip vlan-flooding
To disable, use the no ip vlan-flooding command.
Defaults Disabled.
Command Modes INTERFACE
Command History
Version 8.1.1.0 Introduced on the E-Series ExaScale.
Version 7.4.1.0 Introduced on the E-Series.
Usage
Information
By default, this command is disabled. When enabled, all the Layer 3 unicast routed data traffic
going through a VLAN member port is flooded across all the member ports of that VLAN. There
might be some ARP table entries which are resolved through ARP packets which had Ethernet
MAC SA different from MAC information inside the ARP packet. This unicast data traffic
flooding occurs only for those packets which use these ARP entries.
load-balance (C-Series, S-Series, Z-Series)
By default, for C-Series and S-Series, FTOS uses an IP 4-tuple (IP SA, IP DA, Source Port, and Destination Port) to
distribute IP traffic over members of a Port Channel as well as equal-cost paths. To designate another method to
balance traffic over Port Channel members, use the load-balance command.
C-Series, S-Series, Z-Series, S4810
Syntax
load-balance {ip-selection [dest-ip | source-ip]} | {mac [dest-
mac | source-dest-mac | source-mac]} | {tcp-udp | ingress-port
[enable]}
To return to the default setting (IP 4-tuple), use the no load-balance {ip-selection
[dest-ip | source-ip]} | {mac [dest-mac | source-dest-mac |
source-mac]} | {tcp-udp | ingress-port [enable]}command.
Parameters
ip-selection
{dest-ip | source-
ip}
Enter the keywords to distribute IP traffic based on the following
criteria:
• dest-ip — Uses destination IP address and destination
port fields to hash. The hashing mechanism returns a 3-bit
index indicating which port the packet should be forwarded.
• source-ip — Uses source IP address and source port
fields to hash. The hashing mechanism returns a 3-bit index
indicating which port the packet should be forwarded.
