IPv4 Routing | 691
Usage
Information
This command provides egress port information for a given IP flow. This is useful in
identifying which interface the packet will follow in the case of Port-channel and Equal Cost
Multi Paths. Use this command for routed packed only. For switched packets use the show
port-channel-flow command.
show ip flow does not compute the egress port information when load-balance mac hashing is
also configured due to insufficient information (the egress MAC is not available).
S-Series produces the following error message:
Message 1 %Error: Unable to read IP route table
C-Series produces the message:
%Error: FIB cannot compute the egress port with the current trunk hash
setting.
Example
(E-Series)
FTOS#show ip flow interface Gi 1/8 189.1.1.1 63.0.0.1 protocol tcp source-port
7898 destination-port 8976
flow: 189.1.1.1 63.0.0.1 protocol 6 7868 8976
Ingress interface: Gi 1/20
Egress interface: Gi 1/14 to 1.7.1.2[CAM hit 103710] unfragmented packet
Gi 1/10 to 1.2.1.2[CAM hit 103710] fragmented packet

Parameter
interface
(OPTIONAL) Enter the following keywords and slot/port or number
information:
• For a 1-Gigabit Ethernet interface, enter the keyword GigabitEthernet
followed by the slot/port information.
• For a Loopback interface, enter the keyword Loopback followed by a
number from 0 to 16383.
• For the Management interface, enter the keyword ManagementEthernet
followed by zero (0).
• For the Null interface, enter the keyword null followed by zero (0).
• For a Port Channel interface, enter the keyword port-channel followed by
a number:
C-Series and S-Series Range: 1 to 128
E-Series Range: 1 to 255 for TeraScale and 1 to 512 for ExaScale.
• For a SONET interface, enter the keyword sonet followed by the slot/port
information.
• For a 10-Gigabit Ethernet interface, enter the keyword
TenGigabitEthernet followed by the slot/port information.

by the slot/port information.
• For a VLAN, enter the keyword vlan followed by a number from 1 to
4094.
