Release Notes K.12.26

Enhancements

Troubleshooting

The following situations may occurring when using RL-PACLs.

■ Enhancement (PR_1000374051) — The 5400zl switches are not detecting packets from

an Avaya G700 PBX or Cajun switch due to irregular Ethernet packets sent by those devices.

This is a workaround that will alter the 5400zl software to allow 100Mb operation on the

upcoming "C" revision of the 1000 Base-T Mini-GBICs (J8177C) that fit in the J8705A module.

The port containing the 1000 Base-T Mini-GBIC can be configured with new speed options

of "auto-100," "100-full," and "100-half."

■ Enhancement (PR_1000443349) — This enhancement is to allow the concurrent use of

SFTP with TACACS+ authentication for SSH connections.

Problem Resolution

You try to apply an RL-PACL to a port, but

are informed that there are insufficient

resources.

Hardware resources have been consumed by some combination

of RL-PACLs, other ACLS, other QoS or rate-limiting features or

other features on the switch. Enter the commands show access-

list resources or show qos resources to see what features are

using resources.

The switch is unexpectedly dropping

traffic entering a port and you suspect

the RL-PACL is the issue.

The command show access-list ports <port-list> shows which

ACLs are applied to a port, including regular ACLS and RL-PACLs.

If these are not causing the problem, enter the command show

access-list vlan <vlan-id> to check VLANs.

Additionally, check the configured rate-limit using the show rate-

limit command.

The switch is not rate-limiting traffic

even though an RL-PACL is configured.

Verify that the RL-PACL is configured correctly by entering the

show rate-limit ip access-group <portnum> command. Check that

the ACL name and rate (in kbps) are correctly configured for the

port.

Traffic is only dropped when the rate limit for packets matching

permit statements is exceeded. For example, if an RL-PACL is

configured with a rate-limit of 100 kbps and 100 kbps of traffic

matches permit statements and 100 kbps of traffic matches deny

statements, all 200 kbps of traffic is allowed to pass through the

port.
