Catalyst 6500 SPAN problems - part of the traffic not visible
Consider the following configuration:
hardware: Catalyst 6500E with Supervisor Engine 720
Type : Local Session
Source VLANs :
Both : 10-14,18,189,211,213-214,223-224,240,242,244-245,264-265,267,270,272,274,520,522-523,525,527-533,536-537,539,547
Destination Ports : Te6/1
Egress SPAN Replication State:
Operational mode : Centralized
Configured mode : Centralized (default)
As You can see, there are a lot of VLAN's (and a lot of traffic) going through this SPAN session.
One of the SPAN'ed VLAN's is VLAN10, with following SVI config:
ip address 10.1.10.2 255.255.255.0
ip flow ingress
standby 10 ip 10.1.10.1
standby 10 priority 130
standby 10 preempt
standby 25 ip 10.1.10.4
standby 25 priority 130
standby 25 preempt
standby 35 ip 10.1.10.7
standby 35 priority 130
standby 35 preempt
Problem is, that traffic directed to HSRP gateway in group 10 is not visible in SPAN session. When default gateway on host is changed to virtual address in group 25, traffic from this host appears on SPAN destination port as expected.

Hi, I am seeing quite a few issues with patch install and wanted to
share my experience and workaround to this. Login to admin via CLI, then
access root with the “shell” command Issue “df –h” and you’ll probably
