Global ACL command to delete ACLs bound to an interface

The access-list command now allows the deletion of Access Control Lists (ACLs) bound to an

interface. The following examples show the application of an ACL and the deletion of the ACL that

has been bound to an interface.

1. ACL configuration

Brocade(config)# access-list 102 permit ip any any

2. Application of the ACL to interfaces

Brocade(config)# int eth 1/2

Brocade(config-if-e10000-1/2)# ip access-group 102 in

Brocade(config-if-e10000-1/2)# exit

Brocade(config)# int eth 4/3

Brocade(config-if-e10000-4/3)# ip access-group 102 out

Brocade(config-if-e10000-1/2)# exit

3. Deleting an ACL definition

Brocade(config)# no access-list 102 permit ip any any

Brocade(config)# ACL 102 is in use. Would you like to delete it? (Y/N)

Changing the router ID

In most configurations, a Brocade device has multiple IP addresses, usually configured on different

interfaces. As a result, a Brocade device’s identity to other devices varies depending on the

interface to which the other device is attached. Some routing protocols, including OSPF and BGP4,

identify a Brocade device by just one of the IP addresses configured on the Brocade device,

regardless of the interfaces that connect the Brocade devices. This IP address is the router ID.

NOTE

RIP does not use the router ID.

NOTE

If you change the router ID, all current BGP4 sessions are cleared.

By default, the router ID on a Brocade device is one of the following:

• If the device has loopback interfaces, the default router ID is the IP address configured on the

lowest numbered loopback interface configured on the Brocade device. For example, if you

configure loopback interfaces 1, 2, and 3 as follows, the default router ID is 10.9.9.9/24:

• Loopback interface 1, 10.9.9.9/24

• Loopback interface 2, 10.4.4.4/24

• Loopback interface 3, 10.1.1.1/24

• If the IP address from loopback1 interface (lowest numbered loopback interface) is removed,

the next lowest loopback interface IP address is selected as router-id.

• If a loopback interface is not configured, then the lowest IP address configured over the

physical interface is selected as the router ID.
