Monitoring and Viewing the MLS Configuration

Commands on each MLS−SE and MLS−RP to monitor and view the configurations of each device are different. Let’s take a look at the following commands:

Viewing the MLS aging configuration on a Catalyst 6000

Displaying the IP MLS configuration

Viewing MLS−RPs

Viewing MLS−RP specifics

Displaying MLS VTP domain information

Viewing the MLS VLAN interface information

Viewing MLS statistics on the Catalyst 5000

Viewing MLS statistics on the Catalyst 6000

Viewing MLS entries

Viewing the MLS Aging Configuration on a Catalyst 6000

To see the MLS aging configuration on a Catalyst 6000, use the show mls aging command as shown here:

MLS−RP# show mls aging

 

 

 

enable timeout packet threshold

 

—————— ——————— —————— —————————

normal aging false

900

N/A

Displaying the IP MLS Configuration

To display the MLS configuration for the MLS−RP, use the following command:

MLS−RP# show mls rp

The output should look similar to this:

ip multilayer switching is globally enabled ipx multilayer switching is globally enabled

ipx mls inbound acl override is globally disabled mls id is 0008.80e4.abd2

mls ip address 38.187.127.254 mls ip flow mask is destination mls ipx flow mask is unknown

number of domains configured for mls 1

Viewing MLS−RPs

To see which MLS−RPs are configured on an MLS switch, use the following command:

MLS−RP> (enable) show mls include Included MLS−RP

———————————————————

38.187.128.254

38.187.127.254 Console> (enable)

Viewing MLS−RP Specifics

To display MLS information for a specific MLS−RP on an MLS switch, enter the following:

MLS−RP> (enable) show mls rp 38.187.128.254

Displaying MLS VTP Domain Information

To display the MLS VTP domain information, enter the following command:

MLS−RP# show mls rp vtp−domain coriolis vlan domain name: coriolis

current flow mask: ip−flow current sequence number: 88452194 current/maximum retry count: 0/10 current domain state: no−change

current/next global purge: false/false current/next purge count: 0/0

domain uptime: 13:07:36

keepalive timer expires in 8 seconds retry timer not running

change timer not running fcp subblock count = 7

1 management interface(s) currently defined: fastethernet 1/1 on Vlan2

1 mac−vlan(s) configured for multi−layer switching:

mac 00e0.befc.4000 vlan id(s)

2

router currently aware of following 1 switch(es): switch id 0080.abac.24ec

Viewing the MLS VLAN Interface Information

To view the MLS information about specific interfaces, use the show mls rp interface vlan command as shown here:

MLS−RP# show mls rp interface vlan 2 mls active on Vlan2, domain coriolis

Viewing MLS Statistics on the Catalyst 5000

This command illustrates how to display MLS information on the Catalyst 5000:

CAT5000> (enable) show mls Multilayer switching enabled

Multilayer switching aging time = 256 seconds

Multilayer switching fast aging time = 0 seconds, packet threshold = 1 Destination−ip flow

Total packets switched = 105483 Active entries = 513

Netflow data export enabled

Netflow data export configured for port 8010 on host 10.1.1.25

Total packets exported

= 20

Viewing MLS Statistics on the Catalyst 6000

On the Catalyst 6000, you can get information similar to that provided by the previous command by entering the following:

CAT6000> (enable) show mls ip
