deny (Management)

To set permit rules (ACEs) for the management access list (ACL), use the deny Management Access-list Configuration mode command.

Syntax

deny [interface-id] [service service]

deny ip-source {ipv4-address | ipv6-address/ipv6-prefix-length} [mask {mask |

prefix-length}] [interface-id] [service service]

Parameters

• interface-id—(Optional) Specifies an interface ID. The interface ID can be one of the following types: Ethernet port, Port-channel or VLAN
• service service—(Optional) Specifies the service type. Possible values are: Telnet, SSH, HTTP, HTTPS and SNMP.
• ipv4-address—Specifies the source IPv4 address.
• ipv6-address/ipv6-prefix-length—Specifies the source IPv6 address and source IPv6 address prefix length. The prefix length must be preceded by a forward slash (/). The parameter is optional.
• mask mask—Specifies the source IPv4 address network mask. The parameter is relevant only to IPv4 addresses.
• mask prefix-length—Specifies the number of bits that comprise the source IPv4 address prefix. The prefix length must be preceded by a forward slash

(/). The parameter is relevant only to IPv4 addresses. (Range: 0–32)

Default Configuration

No rules are configured.

Command Mode

Management Access-list Configuration mode

User Guidelines

Rules with ethernet, VLAN, and port-channel parameters are valid only if an IP address is defined on the appropriate interface.

Example

The following example denies all ports in the ACL called mlist.

switchxxxxxx(config)# management access-list mlist switchxxxxxx(config-macl)# deny

permit (Management)

To set permit rules (ACEs) for the management access list (ACL), use the permit Management Access-list Configuration mode command.

Syntax

permit [interface-id] [service service]

permit ip-source {ipv4-address | ipv6-address/ipv6-prefix-length} [mask {mask |

prefix-length}] [interface-id] [service service]

Parameters

• interface-id —(Optional) Specify an interface ID. The interface ID can be one of the following types: Ethernet port, Port-channel or VLAN
• service service — (Optional) Specifies the service type. Possible values are: Telnet, SSH, HTTP, HTTPS and SNMP.
• ipv4-address — Specifies the source IPv4 address.
• ipv6-address/ipv6-prefix-length — Specifies the source IPv6 address and source IPv6 address prefix length. The prefix length must be preceded by a forward slash (/). The parameter is optional.
• mask mask — Specifies the source IPv4 address network mask. This parameter is relevant only to IPv4 addresses.
• mask prefix-length — Specifies the number of bits that comprise the source IPv4 address prefix. The prefix length must be preceded by a forward slash

(/). This parameter is relevant only to IPv4 addresses. (Range: 0–32)

Default Configuration

No rules are configured.

Command Mode

Management Access-list Configuration mode

User Guidelines

Rules with Ethernet, VLAN, and port-channel parameters are valid only if an IP address is defined on the appropriate interface.

Example

The following example permits all ports in the ACL called mlist

switchxxxxxx(config)# management access-list mlist switchxxxxxx(config-macl)# permit

management access-list

To configure a management access list (ACL) and enter the Management

Access-list Configuration mode, use the management access-list Global Configuration mode command. To delete an ACL, use the no form of this command.

Syntax management access-list name no management access-list name

Parameters

name—Specifies the ACL name. (Length: 1–32 characters)

Default Configuration

N/A

Command Mode

Global Configuration mode

User Guidelines

Use this command to configure a management access list. This command enters the Management Access-list Configuration mode, where the denied or permitted access conditions are defined with the deny and permit commands.

If no match criteria are defined, the default value is deny.

When re-entering the access-list context, the new rules are entered at the end of the access list.

Use the management access-class command to select the active access list.

The active management list cannot be updated or removed.

For IPv6 management traffic that is tunneled in IPv4 packets, the management ACL is applied first on the external IPv4 header (rules with the service field are ignored), and then again on the inner IPv6 header.

Examples

Example 1 – The following example creates a management access list called mlist, configures management te1/0/1 and te1/0/9, and makes the new access list the active list.

switchxxxxxx(config)# management access-list mlist switchxxxxxx(config-macl)# permit te1/0/1 switchxxxxxx(config-macl)# permit te1/0/9 switchxxxxxx(config-macl)# exit switchxxxxxx(config)#

Example 2 – The following example creates a management access list called ‘mlist’, configures all interfaces to be management interfaces except te1/0/1 and te1/0/9, and makes the new access list the active list.

switchxxxxxx(config)# management access-list mlist switchxxxxxx(config-macl)# deny te1/0/1 switchxxxxxx(config-macl)# deny te1/0/9 switchxxxxxx(config-macl)# permit switchxxxxxx(config-macl)# exit switchxxxxxx(config)#

management access-class

To restrict management connections by defining the active management access list (ACL), use the management access-class Global Configuration mode command. To disable management connection restrictions, use the no form of this command.

Syntax

management access-class {console-only | name} no management access-class

Parameters

• console-only—Specifies that the device can be managed only from the console.
• name—Specifies the ACL name to be used. (Length: 1–32 characters)

Default Configuration

The default configuration is no management connection restrictions.

Command Mode

Global Configuration mode

Example

The following example defines an access list called mlist as the active management access list.

switchxxxxxx(config)# management access-class mlist

show management access-list

To display management access lists (ACLs), use the show management access-list Privileged EXEC mode command.

Syntax show management access-list [name]

Parameters

name—(Optional) Specifies the name of a management access list to be displayed. (Length: 1–32 characters)

Default Configuration

All management ACLs are displayed.

Command Mode

Privileged EXEC mode

Example

The following example displays the mlist management ACL.

switchxxxxxx# show management access-list mlist m1 -deny service telnet permit te1/0/1 service telnet   ! (Note: all other access implicitly denied) console(config-macl)#

show management access-class

To display information about the active management access list (ACLs), use the show management access-class Privileged EXEC mode command.

Syntax show management access-class

Parameters

This command has no arguments or keywords.

Command Mode

Privileged EXEC mode

Example

The following example displays the active management ACL information.

switchxxxxxx# show management access-class   Management access-class is enabled, using access list mlist
